以甲基丙基三异丙氧基钛（MTPT）和醇氧钡为原料成功合成了钛酸钡(BaTiO3)/聚合物复合材料。在90 ~ 150°c的温度下，偶氮二异丁腈对MTPT进行自由基聚合，1h NMR谱显示MTPT与钡烷氧化物反应生成络合物烷氧化物。复合醇盐经聚合和水解后形成batio3颗粒/聚合物。透射电镜观察表明，batio3晶粒大小约为3nm，分散在聚合物基体中。
Barium titanate (BaTiO3)/polymer composite was successfully synthesized by methacryltriisopropoxytitanium (MTPT) and barium alkoxide. MTPT undergoes radical polymerization using azobisisobutyronitrile at temperatures from 90 to 150°C.1H NMR spectra showed that MTPT reacted with barium alkoxides yielding a complex alkoxide. BaTiO3particles/polymer was formed after the polymerization and hydrolysis of the complex alkoxide. The transmission electron microscopic observation revealed that crystalline BaTiO3particles of around 3 nm in size were dispersed in the polymer matrix.
