Abstract: Proposed are copper sulfide nanoparticles having a core-shell structure included in a coating composition for blocking near-infrared light, and a method of manufacturing the same. More particularly, a method of manufacturing copper sulfide nanoparticles having a core-shell structure includes manufacturing CuS nanoparticles, manufacturing Cu2-xS nanoparticles by heating a mixed solution of the CuS nanoparticles, a reducing agent, and a solvent, and manufacturing Cu2-xS@Cu2-yO core-shell nanoparticles by heating a mixed solution of the Cu2-xS nanoparticles, an oxidizing agent, and a solvent.

Abstract: Proposed is a paint protection film with excellent self-healing ability, stain resistance, and weather resistance. When being applied to vehicles, damage to the painted surface, such as chipping, scratches, and the like occurring in the middle of driving, can be effectively prevented. In addition, even when exposed to the external environment for a long period of time, the transparency of the film can be maintained. Furthermore, discoloration or stains caused by contaminants can be prevented, thereby maintaining aesthetics.
