- A detoxification coating achieved on various materials by complexation of a detoxification catalyst through functional polymer design - Expected to contribute to next-generation protective suits and equipment, as well as to detoxification treatment of chemical leakage Highly toxic organic compounds are colorless, odorless, and can be used to perpetrate massacres in very small amounts; thus, their use is prohibited by the Chemical Weapons Convention worldwide. Nevertheless, there have been reports of chemical weapon use recently, and therefore, there is an emerging need to develop protective materials against such threats. Currently, activated charcoals are used in protective suits and gas masks to remove toxic chemicals by absorption, but they have their own problems, such as secondary contamination; thus, the development of detoxification catalysts that can fundamentally remove toxicity is required. The Korea Institute of Science and Technology (KIST, President Yoon Seokjin) announced that the research team led by Dr. Baek Kyung Youl, a senior researcher at the Materials Architecturing Research Center, succeeded in developing a detoxification composite that can be easily processed into a coating material, continuing on their success in developing a nano-based detoxification catalyst in 2019. The previously developed metal-organic framework (MOF) detoxification catalyst had high performance, but was in the form of particles that break like sand; thus, it had not been put into practical use in coating military uniforms and equipment. To overcome this problem, Baek’s research team designed a functional polymer and mixed it with a detoxification catalyst to develop a detoxification technology that can be processed into films and fibers while maintaining its properties. The research team developed a new functional polymeric support that improves processability while maintaining the high reactivity of the previously developed nanometer-level zirconium (Zr)-based detoxification catalyst, and used it to make a mixed compound that can be used as a detoxification catalyst. It was confirmed to be practically applicable in a detoxification performance test using an actual chemical weapon, the nerve agent soman (GD), on military uniforms and equipment coated with the compound. Dr. Baek of KIST said, “What is different about this compound is that it can remove the toxicity of chemical weapons easily and coat large areas quickly using a simple spray process rather than the conventional electrospinning method”, and that “It is expected that the spray coating can be applied to military uniforms and equipment to prevent contamination and be used to remove toxic agents from equipment, protecting the lives of soldiers and civilians from highly toxic chemical agents.” This study was conducted with the support of the K-DARPA project of KIST and in cooperation with KIST’s Department of National Security, Disaster and Safety Technology. The results of the study have been published online in the latest issue of ACS Applied Materials & Interfaces (IF: 10.383, JCR Top 14.05%).

- Photocatalysis-based Prompt and Complete Removal of Trace Amount of Alcohol in Water Alcohols are used to remove impurities on the surface of semiconductors or electronics during the manufacturing process, and wastewater containing alcohols is treated using reverse osmosis, ozone, and biological decomposition. Although such methods can lower the alcohol concentration in wastewater, they are ineffective at completely decomposing alcohols in wastewater with a low alcohol concentration. This is because alcohol is miscible in water, making it impossible to completely separate from alcohol using physical methods, while chemical or biological treatments are highly inefficient. For this reason, wastewater with a low alcohol concentration is primarily treated by diluting it with a large amount of clean water before its discharge. The Korea Institute of Science and Technology (KIST, President Seok-Jin Yoon) has announced that a research team led by Dr. Sang Hoon Kim and Dr. Gun-hee Moon of Extreme Materials Research Center developed a photocatalyst that can completely decompose a trace amount of alcohol in water within a short duration by adding a very trace amount of copper to iron oxide, which is used as a catalyst during the advanced oxidation process. The research team employed Fenton oxidation that uses oxidizing agents and catalysts during the advanced oxidation process for water treatment. Usually alcohols were used as reagents to verify radical production during Fenton oxidation in other advanced oxidation process (AOP) studies, they were the target for removal from semiconductor wastewater in this research. This water treatment technology is expected to dramatically reduce the cost and water resources invested into the treatment of semiconductor wastewater. In the past, clean water with a volume 10 times higher than that of the wastewater under treatment was required for dilution of the wastewater in order to reduce the alcohol concentration of 10 ppm in the wastewater to less than 1 ppm. If the photocatalyst developed by the KIST is used for water treatment, water resources can be saved. The research team applied the photocatalyst to wastewater from a semiconductor factory to prove that alcohol decomposition levels similar to those observed in the laboratory could be achieved in industrial practice. “As large-scale semiconductor production lines are established, we expect that there will be a rapid increase in the demand for the treatment of semiconductor wastewater,” said Dr. Kim. “The results of our research will provide a solution to effectively treat semiconductor wastewater using less resources and at a lower cost,” he added.

Hydrogen is considered a future clean energy source, and thus, building infrastructure and developing core technologies for hydrogen production, storage, transportation, and utilization has attracted significant attention. Among the various hydrogen storage methods, metal hydride-based hydrogen storage systems are considered the safest method to store hydrogen. The Korea Institute of Science and Technology (KIST, President Seokjin Yoon), headed by Dr. Dong Won Chun and Dr. Jin-Yoo Suh, the research teams of the Energy Materials Research Center, and Prof. Kyu Hyoung Lee from the Yonsei University (President Seoung-Hwan Suh), along with their research team, succeeded in the real-time monitoring of the dehydrogenation of metal hydride composites made of Mg and Fe with high nanometer-scale resolution. The joint research team observed the transition of hydrogen atoms from their initial state inside a metal hydride solid to the gaseous state as they move from the outside and calculated the amount of hydrogen that remains inside the metal hydride after the dehydrogenation process. Meanwhile, physical properties of metal hydride were investigated by observing nano-sized samples through an electron microscope; therefore, the reliability of results is questionable. However, the researchers verified that the same phenomenon is reproduced in an experiment when the nano-sized sample (100 nm) is compared with bulk-sized metal hydrate samples (several mm) produced for commercialization. By minimizing sample damage caused by the electron beam, it is possible to observe the movement of hydrogen within the metal, bringing a new phase in the development of hydrogen storage. Dr. Chun said "Hydrogen, with atomic number 1, has one electron and one proton, so it is difficult to observe its movement at the current level of technology, which analyzes the signal of electrons or protons. The research team has introduced a new methodology to observe hydrogen movement within solids. We will apply this technology to the new national challenge of developing solid hydrogen storage systems to build a safe hydrogen storage infrastructure. The final goal is to make hydrogen energy widely available in our daily lives." The research was supported by the Ministry of Science and ICT (Minister Jong-Ho Lee) and was carried out as a major KIST project and as a mid-career researcher project by the National Research Foundation of Korea. The results were published in the latest issue of “Advanced Functional Materials”, a specialized journal on materials and energy. Figure 1.

- Self-reporting and self-healing coatings similar to human skin - High re-usability of coating reduces waste generation by maintaining functionality Skin-like polymeric coatings are applied to the surfaces of automobiles, ships, and buildings to protect them from the external environment. As it is difficult to determine whether the currently used coatings are already damaged or not, these non-reusable coatings must be regularly replaced, leading to a large amount of waste generation and high disposal costs. The Korea Institute of Science and Technology (KIST, President Seok-Jin Yoon) announced that Dr. Tae Ann Kim’s team at the Soft Hybrid Materials Research Center has developed a polymeric coating wherein the damaged area changes color, enabling immediate detection and high temperature self-healing. Existing studies on damage-reporting and self-healing polymeric coatings involve the use of extremely small capsules containing functional agents. However, these capsules cannot be used again for subsequent damage detection and self-healing if broken. The KIST research team has developed a thermoset polymer that can recover its original chemical structure after being disrupted by an external stimulus, thereby allowing this material to self-report damage and self-heal multiple times. In this study, a mechanochromic molecule, which changes color when an external force is applied due to a specific bond cleavage, and a thermoset polymer containing a molecule that can be separated and re-formed by temperature were synthesized. When a force is applied to a mechanochromic molecule, a certain bond is broken, thus changing into a form that can exhibit color. The damaged part of the synthesized polymeric coating changed to purple. When a temperature of 100 °C or higher was applied, the material became processable and was physically healed and became colorless. The research team used molecular dynamics simulations to predict and confirm that only certain desired chemical bonds are selectively cleaved when a mechanical force is applied to yield a colored structure; the functionality was implemented by synthesizing the actual coating agent. The novel multifunctional polymeric coating developed herein can be extensively used in automotive, marine, defense, timber, railway, highway, and aerospace industries, and can significantly contribute toward the reduction of industrial waste. In addition, it can be used as an artificial skin for robots, such as humanoids, since its functionality is similar to that of skin and it does not require an external energy source. Dr. Tae Ann Kim of KIST said, “This study reports a method for the simultaneous realization of damage detection and self-healing technology without any external agents such as capsules.” He added, “However, even if repeated self-healing is possible, it cannot be used permanently. Therefore, additional research is underway to transition materials that have reached their lifespan into materials that are harmless to the environment or convert them into a re-cyclable form.” [Image] [Fig. 1] Schematic of mechanochromic and self-healing thermosets [Fig. 2] Mechanochromic and self-healing coatings on diverse substrates

- Discovery of dispersing solvent parameters affecting ionomer microporous structure - Performance improvement of proton-exchange membrane hydrogen fuel cells under high-temperature and non-humidified conditions A hydrogen fuel cell, which is a device that generates electrical energy through the reaction of hydrogen and oxygen in air, is gaining increasing attention as an eco-friendly power-generating device that do not emit pollutants. Among the various hydrogen fuel cells, proton-exchange membrane fuel cells (PEMFCs), which use ion-exchangeable polymer membranes as electrolytes, are relatively lightweight and have a faster start-up time. Owing to these characteristics, they are actively studied as a power source for homes and automobiles. Owing to their high electrochemical reaction rates and strong resistance to impurities at high operating temperatures, PEMFCs are ideal for applications in high-performance transportation, such as trucks, subways, trains, airplanes, and ships. However, a separate cooling system is required at high temperatures (>100 °C) to prevent ionic conductivity reduction triggered by evaporation in polymers. The weight added by cooling systems decreases the efficiency of PEMFCs. To use PEMFCs without a cooling system, high-temperature performance improvement and (80–200 ℃) non-humidification conditions are essential. The Korea Institute of Science and Technology (KIST, President Seok-Jin Yoon) announced that Dr. Sung-Soo Lee’s team at the Material Structure Control Research Center, KIST, South Korea, and Dr. Yu-Seung Kim’s team at the Los Alamos Research Center (LANL), the U.S, have jointly developed a platform for controlling the microporous structure of ionomers, which is the key to improving the PEMFC performance. When polymer-containing phosphonic acid (RPO3H2) and polymer-containing sulfonic acid (RSO3H) combine, hydrogen from the sulfonic acid, which has a higher acid strength, is transferred to the phosphonic acid, thereby forming a protonated phosphonic acid ionomer. Using such a composite ionomer enables waterless ionic conduction, resulting in an increased performance of hydrogen fuel cells, even under high-temperature and non-humidified conditions. Further performance improvement can be expected through increased usage of reactive gases, such as hydrogen and oxygen. The KIST and LANL joint research team induced the accessibility of reactive gases by manipulating a composite ionomer to obtain a microporous structure. The team discovered the dependency of the composite ionomer’s microporous structure on the solvent in which it is dispersed, as well as a direct correlation between the dispersion solvent’s pKa (acid strength) and the phosphonic acid ionomer’s microporous structure. Subsequently, a performance evaluation of a high-temperature-hydrogen fuel cell confirmed that the composite ionomer’s microporous structure positively affected the performance of fuel cells. Dr. Sung-Soo Lee of KIST said, “The achievement is in discovering how important ionomer dispersion solvent pKa is in high-temperature-hydrogen fuel cells.” He revealed the significance of the study, adding, “We have expanded the use of hydrogen fuel cells from small transportation to bigger mobility such as trucks and ships.” This research was performed as part of the Advanced Research Projects Agency-Energy of the US Department of Energy, the Material Innovation Lead Project of the Ministry of Science and ICT (Minister Jong-Ho Lee), and the major projects of KIST. The research results are published in ‘ACS Energy Letters’ (IF:23.101, JCR top 3.302%).

- Improved efficiency of wireless energy transfer of ultrasonic waves by triboelectric power generation - Ultrasonic waves have applications in wireless charging of batteries underwater or in body-implanted electronic devices As population ages and with the advancements in medical technology, the number of patients using implanted electronic devices, such as artificial pacemakers and defibrillators, is increasing worldwide. Currently, the batteries of body-implanted devices are replaced by an incision surgery, which may lead to health complications. Accordingly, a new charging technique by wireless energy transfer is emerging that can also be used to charge the batteries of underwater devices, such as sensors, that are used for monitoring the conditions of submarine cables. The Korea Institute of Science and Technology (KIST, President: Seok-Jin Yoon) announced that a research team led by Dr. Hyun-Cheol Song at the Electronic Materials Research Center developed an ultrasonic wireless power transmission technology that can be applied in the above-mentioned research areas. Electromagnetic (EM) induction and magnetic resonance can be used in wireless energy transfer. EM induction is presently being used in smartphones and wireless earphones; however, its usage is limited because EM waves cannot pass through water or metal, resulting in short charging distance. In addition, this method cannot be easily used to recharge implanted medical devices as the heat generated during charging is harmful. The magnetic resonance method requires that the resonant frequencies of the magnetic field generator and transmitting device are exactly the same; moreover, a risk of interference with other wireless communication frequencies, such as Wi-Fi and Bluetooth, exists. The KIST team, therefore, adopted ultrasonic waves as an energy transmission medium, instead of EM waves or magnetic fields. Sonar, which uses ultrasound waves, is commonly used in underwater environments, and the safety of using ultrasonic waves in the human body has been guaranteed in various medical applications, such as organ or fetal condition diagnosis. However, the existing acoustic energy transfer methods are not commercialized easily due to the low transmission efficiency of acoustic energy. The research team developed a model that receives and converts ultrasonic waves into electrical energy using the triboelectric principle that allows for the conversion of small mechanical vibrations into electrical energy effectively. By adding a ferroelectric material to the triboelectric generator, the ultrasonic energy transfer efficiency was significantly improved from less than 1% to more than 4%. Moreover, charging of more than 8 mW power at a distance of 6 cm was possible, which was sufficient to simultaneously operate 200 LEDs or to communicate Bluetooth sensor data underwater. In addition, the newly developed device had high energy conversion efficiency and generated marginal amounts of heat. Dr. Song explained the significance of the results as follows: “This study demonstrated that electronic devices can be driven by wireless power charging via ultrasonic waves. If the stability and efficiency of the device are further improved in the future, this technology can be applied to supply power wirelessly to implantable sensors or deep-sea sensors, in which replacing batteries is cumbersome.” Image Schematic illustration of wirelessly charging a body-implanted electronic device using an ultrasonic probe Wireless acoustic energy transfer into implantable devices within pork (skin and flesh) as a substitute for the human body Underwater wireless acoustic energy transfer system that can simultaneously operate 200 LEDs and a wireless sensor in real time

- Realization of stretchable, adhesive, and mechanically deformable batteries that effectively transfer ions - Every component was designed to be stretchable to enable printing on clothing and use in wearable devices A Korean research team has developed a soft, mechanically deformable, and stretchable lithium battery which can be used in the development of wearable devices, and examined the battery’s feasibility by printing them on clothing surfaces. The research team, led by Dr. Jeong Gon Son from the Soft Hybrid Materials Research Center at the Korea Institute of Science and Technology (KIST; President: Seok-Jin Yoon), announced that they had developed a lithium battery wherein all of the materials, including the anode, cathode, current collector, electrolytes, and encapsulant, are stretchable and printable. The lithium battery developed by the team possesses high capacity and free-form characteristics suitable for mechanical deformation. Owing to the rapidly increasing demand for high-performance wearable devices such as smart bands, implantable electronic devices such as pace-makers, and soft wearable devices for use in the realistic metaverse, the development of a battery that is soft and stretchable like the human skin and organs has been attracting interest. The hard inorganic electrode of a conventional battery comprises the majority of the battery’s volume, making it difficult to stretch. Other components, such as the separator and the current collector for drawing and transferring charges, must also be stretchable, and the liquid electrolyte leakage issue must also be resolved. To enhance stretchability, the research team avoided using materials as had been done in other studies which were unnecessary for energy storage, such as rubber. Then, a new soft and stretchable organic gel material was developed and applied based on the existing binder material. This material firmly holds the active electrode materials in place and facilitates the transfer of ions. In addition, a conductive ink was fabricated using a material with excellent stretchability and gas barrier properties to serve as as a current collector material that transfers electrons and an encapsulant which can function stably even at a high voltage and in various deformed states without swelling due to electrolyte absorption. The battery developed by the team is also able to incorporate existing lithium-ion battery materials, as they exhibit excellent energy storage density (~2.8 mWh/cm2) of a level similar to that of commercially available hard lithium-ion batteries at a driving voltage of 3.3 V or higher. All of the constituent components of the team's stretchable lithium-ion battery possess the mechanical stability to maintain their performance even after repeated pulling of the battery 1,000 or more times, a high stretchability of 50% or above, and long-term stability in air. Moreover, the research team directly printed the electrode and current collector materials which they had developed on either side of an arm warmer made of spandex and applied a stretchable encapsulant to the material, demonstrating the ability to print a stretchable high-voltage organic battery directly on clothing. Using the resulting battery, the research team was able to continuously power a smart watch even when it was being put on, taken off, or stretched. Dr. Son at KIST stated that his team has developed a stretchable lithium-ion battery technology which provides both structural freedom as a result of the battery’s free-form configuration allowing for it to be printed on materials such as fabrics, and material freedom due to being able to use existing lithium-ion battery materials, in addition to stretch stability which allows for high energy density and mechanical deformation. He also stated that the stretchable energy storage system developed by his team is expected to be applicable to the development of various wearable or body-attachable devices. This study was supported by the Mid-Career Research Program of the National Research Foundation of Korea, and the KIST Institutional Program and K-Lab Program funded by the Ministry of Science and ICT (Minister: Hye-Sook Lim). The research results were published in ACS Nano (IF: 15.881).
