Coating composition comprising copper sulfide core-shell nanoparticle for selectively shielding near infrared ray

摘要

The present invention relates to a coating solution composition having a selective blocking function in the near-infrared region containing copper sulfide nanoparticles having a core-shell structure. The coating solution composition has excellent blocking rate against infrared rays in a wide area, and also has excellent visible light transmittance, excellent light resistance and heat resistance of the coating film, and excellent durability. And it is possible to provide a variety of glass products such as building glass for heat shielding, automobile windows using the same.
