Effects of Excess Cu Addition on Photochromic Properties of AgCl-Urethane Resin Composite Films

الملخص EN

AgCl-resin photochromic composite films were prepared using AgNO3, HCl-EtOH, CuCl2 ethanol solutions, and a urethane resin as starting materials.

The AgCl particle size in the composite films, which was confirmed via TEM observations, was 23–43 nm.

The AgCl composite films showed photochromic properties: coloring induced by UV-vis irradiation and bleaching induced by cessation of UV-vis irradiation.

The coloring and bleaching speed of the composite film increases with increasing CuCl2 mixing ratio.
