摘要：

TiO2-SnO2 nanoparticles with an average diameter of 3 similar to 5 nm were synthesized by hydrolysis of titanium tetraisopropoxide (TTIP) and tin chloride to depress the photocatalytic activity of TiO2 nanoparticles. Organic-inorganic hybrid coating solutions were prepared by reacting the TiO2-SnO2 nanoparticles with 3-glycidoxypropyl trimethoxysilane (GPTMS) by the sol-gel method. The hard coating films with high refractive index were obtained by curing thermally at 120 degrees C after spin-coating the coating solutions on the polycarbonate (PC) sheets. The coating films from TiO2 SnO2 nanoparticles showed an improved pencil hardness of 3H compared to 2H of the coating films from TiO2 nanoparticles. Besides, the refractive index of the coating films from TiO2-SnO2 nanoparticles enhanced from 1.543 to 1.623 at 633 nm as the Sn/Ti molar ratio increased from 0 to 0.5.
