Abstract:
Poly(EA-MAn-APTES)/silica hybrid materials were successfully prepared from Ethyl acrylate(EA), maleic anhydride(MAn)and tetraethoxysilane(TEOS)in the presence of a coupling agent 3-aminopropyltriethoxysilane(APTES), by free-radical solution polymerization and in situ sol-gel process.The mass fraction of TEOS varied from 0 to 25%.The hybrid materials were characterized by the methods of FT-IR spectra, solvent extraction, scanning electron microscope(SEM), transmission electron microscope(TEM), differential scanning calorimetry(DSC)and thermogravimetric analysis(TGA)measuring apparatus to get their structures, gel contents, morphologies, particle sizes and thermal performances.The results show that the covalent bonds are between organic and inorganic phases, gel contents in the hybrid materials are much higher, the SiO2 phase is well dispersed in the polymer matrix, silicon dioxide exist at nanoscale in the composites and have excellent thermal stability.
采用γ-氨丙基三乙氧基硅烷(APTES)作为偶联剂, 以丙烯酸乙酯(EA)、顺丁烯二酸酐(MAn)和正硅酸乙酯(TEOS)为原料, 通过自由基溶液聚合和溶胶-凝胶过程制得了P(EA-MAn-APTES)/二氧化硅有机-无机杂化材料, 其中TEOS的质量分数从0变化至25%.利用傅立叶红外(FT-IR)光谱、溶胶抽取、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、示差扫描量热法(DSC)和热重分析(TGA)性能测试装置对材料的结构、凝胶含量、表面形貌、粒子大小和热性能进行了表征.结果表明:有机相与无机相之间是以共价键结合的, 杂化材料中凝胶的含量较高, 聚合物基体中SiO2是纳米复合的, 具有较好的分散性和热稳定性.
