摘要：

Novel nanocomposites of TiO-ZrO2 nanoparticles and thiol-acrylate resin, with high refractive index, high transparency, good thermal stability and mechanical properties were prepared via UV (Ultraviolet rays)-induced crosslinking polymerization. In this work, TiO2 nanoparticles were synthesized, and its surface treatment was performed with ZrO2 to depress the photocatalytic activity of TiO2. No aggreaation of TiO2-ZrO2 nanoparticles was found after mixing with photocrosslinkable materials and transparent coatings and blocks were obtained. Thiol-acrylate was used as an organic matrix with high refractive index and as a promoter of UV curing reaction. Transmission electronic microscopic studies (TEM) of nanocomposites showed that the TiO2-ZrO2 nanoparticles with a diameter 3-6 nm were dispersed in the organic matrix and maintained their original size before immobilization.
