摘　　要：通过超声分散和原位聚合法制备了以s-BPDA/1,3,4-APB为树脂基体,以具有不同SiO2添加量的新型球型SiO2/聚酰亚胺杂化薄膜,所制备的杂化薄膜具有优异的力学、热学和耐电晕性能。通过SEM、TEM、FT-IR、UV-vis、DSC、TGA等实验手段对产物进行了分析和表征,并系统研究了SiO2的添加量对杂化薄膜的力学性能、热学性能和电学性能的影响规律。A series of spherical SiO2/PI hybrid films were prepared by incorporation of spherical SiO2 particles with different content in the s-BPDA/1,3,4-APB matrix resin via ultrasonic dispersion and in-situ multiphase polymerization, which possessed excellent thermal stabilities, good mechanical properties as well as outstanding electrical insulating properties. The prepared samples were characterized by SEM, TEM, FT-IR, UV-vis, DSC and TGA methods. The effects of SiO2 content on the mechanical, thermal and electrical properties of SiO2/PI hybrid films were investigated.
