Professor Jin Chul Kim's research lab specializes in the design and development of smart, functional materials with a focus on self-healing polymers, photocatalytic nanomaterials, and energy-efficient devices. The lab explores dynamic polymer networks integrated with photothermal agents for applications in self-healing coatings, transparent conductive films, and sustainable chemical conversion processes. Key research directions include the synthesis of hybrid nanomaterials for enhanced photocatalysis under visible light and the engineering of thermoacoustic loudspeakers with intrinsic self-repairing capabilities. The lab emphasizes practical applications in optics, renewable energy, and advanced electronics.

A new composite consisting of TiO(2) nanotubes and CdS nanoparticles, where CdS particles bind covalently to the titania surface through a bifunctional organic linker, was successfully fabricated; this titania nanotube-based composite shows enhanced photocatalytic activity under visible-light irradiation.
The use of formic acid leads to the complete decomposition of alkali lignin and affords high-yield aromatic monomers, while at the same time suppress consumption of solvent used for the lignin conversion.
Dynamic polymer networks containing photothermal materials have been reported to demonstrate highly efficient intrinsic self-healing under irradiation. In particular, organic near-infrared-absorbing ionic salts, such as diimmonium dyes, function as transparent polymer heaters and can enhance the self-healing properties of clearcoats. In this study, we designed a self-healing automotive clearcoat with a reversible polymer network based on acryl polyol (AP) and dynamic hindered urea (HU) bonds and
Thermoacoustic (TA) loudspeakers have garnered significant attention in recent times as a novel film speaker that utilizes temperature oscillation to vibrate the surrounding air. Conventional film-type TA loudspeakers are known to experience problems when external environments damage their conductive networks, causing them to malfunction. Therefore, introducing self-healing polymers in TA loudspeakers could be an effective way to restore the surface damage of conductive networks. In this study,
