摘要

以 1，2-乙二硫醇、四溴双酚 A环氧树脂和 9，9-二（[2，3-环氧丙氧基）苯基 ]芴为原料，LiOH的甲醇溶液为催化剂，采用巯基 -环氧点击化学反应制备含 S和 Br元素的聚合物基体；以钛酸四丁酯为前驱体，采用溶胶 -凝胶法和分段热固化制备出透明高折射率 TiO₂纳米杂化材料。通过红外光谱、纳米粒度仪、椭圆偏振光谱仪、透射电子显微镜和紫外 -可见分光光度计等仪器对其结构、性能进行表征。结果表明： TiO₂粒子在聚合物基体中成功合成并以纳米尺度均匀分散，材料在可见光区域有很高的透光率，大多在 95%左右；随着 TiO₂粒子杂化量的增加，在 486 nm处的折射率由 1.660 2提高到了 1.756 5，阿贝数由 21.65提高到 34.63。

Abstract

A polymer matrix containing S and Br elements was prepared by means ofthiol-epoxy click chemistry，using epoxy resin of 1，2-ethanedithiol tetrabromobisphenol A and 9，9-Bis[4-（glycidyloxy）phenyl] fluorene as main materials and LiOH methanol solutionas catalyst. The transparent high refractive index TiO₂ nano hybrid materials were prepared by means of sol-gel method and segmental heat curing，using titanium butoxide as precursor andacetylacetone as an alcoholysis control agent. The structure and properties were characterizedby infrared spectroscopy，nanometer particle size analyzer，ellipsometry，transmission electron microscopy and ultraviolet-visible spectrophotometer. The experimental results showed that TiO₂ particles were successfully synthesized and homogeneously dispersed at the nanometerscale in the polymer matrix，and the materials provided high light transmittance in the visible light region，at around 95%. As the amount of hybridization of TiO₂ particles increases，the refractive index at 486 nm increases from 1. 660 2 to 1. 756 5，and the Abbe number increases from 21. 65 to 34. 63.

Key words： refractive index; TiO₂ particles; light transmittance; nano-hybrid materials
