摘　　要：以羟基封端的聚二甲基硅氧烷(PDMS)和正硅酸乙酯为主要原料,通过溶胶-凝胶法成功制备出均匀透明的PDMS/SiO2杂化材料,采用红外吸收光谱、紫外-可见光透过光谱、扫描电子显微镜以及热分析仪对制备的材料进行了表征。结果表明,所制得的杂化材料以化学键相结合,两相分散均匀,可见光区透光率高达90%以上,耐热性能良好。Homogeneous and transparent polydimethylsiloxane/SiO2 organic- inorganic hybrid material was synthesized successfully with HO - terminated PDMS and TEOS via sol - gel process . FTIK, UV - VIS, SEM, TG and DSC analysis methods were used to characterizing the hybrid materials. The results indicate that two phase of the hybrid material are linked by chemical bond and dispersed perfectly. Meanwhile, the materials have a excellent optical transparency and good thermal stability.
