摘要: 由共聚合在PMMA聚合物链段上引入了-Si(OR)3功能团,通过溶胶-凝胶过程合成了PMMA/TiO2杂化聚合物材料.溶剂抽提结果表明有化学键存在的杂化材料体系中凝胶的含量很高.通过FTIR测试对材料结构进行了分析,由TGA、DSC测试分析了杂化材料体系中无机组份的含量对材料性能的影响.

Abstract: In this paper, the PMMA/TiO2 hybrid polymeric materials were prepared by the sol-gel process.In order to introduce the chemical bond between the organic polymer chain and inorganic network in the hybrid, the trimethoxysilyl functional group was introduced on the polymer side chain by copolymerization with 3-(trimethoxysilyl) propyl methacrylate (MSMA).The result of solvent extraction shows that the gel content in the hybrids with the presence of chemical bond through the reaction of MSMAwith titanium(IV) butoxide is much higher.The chemical structure of the hybrid was analyzed by the FTIR, and the effect of inorganic content on the properties of materials were investigated by TGAand DSC.

Key words: Sol-gel process, Hybrid polymeric material, PMMA, Titanium(Ⅳ) butoxide
