Abstract

Organic-inorganic hybrid sols (Ti-O-Si precursor) were first synthesized by the sol-gel method at low addition of water, and were then employed to prepare a highly refractive hybrid optical film. This film was obtained by blending the Ti-O-Si precursor with 2-phenylphenoxyethyl acrylate (OPPEA) to perform photo-polymerization by ultraviolet (UV) irradiation. Results show that the film transparency of poly(Ti-O-Si precursor-co-OPPEA) film is higher than that of a pure poly(Ti-O-Si precursor) film, and that this poly(Ti-O-Si precursor-co-OPPEA) hybrid film exhibits a high transparency of ~93.7% coupled with a high refractive index () of 1.83 corresponding to a thickness of 2.59 μm.

摘要

首先通过溶胶 - 凝胶法在低加水量的条件下合成有机 - 无机杂化溶胶（Ti - O - Si前驱体），然后将其用于制备高折射率杂化光学薄膜。该薄膜是通过将Ti - O - Si前驱体与丙烯酸2 - 苯苯氧基乙酯（OPPEA）混合，经紫外线（UV）照射进行光聚合而获得的。结果表明，聚（Ti - O - Si前驱体 - 共 - OPPEA）薄膜的透明度高于纯聚（Ti - O - Si前驱体）薄膜，并且这种聚（Ti - O - Si前驱体 - 共 - OPPEA）杂化薄膜在厚度为2.59μm时具有约93.7%的高透明度以及1.83的高折射率（）。
