摘　　要：以聚酰亚胺作为高聚物反应基体,通过正硅酸乙酯(TEOS)和异丙醇铝的水解缩合反应,使之和聚酰胺酸发生溶胶-凝胶反应,从而制备出不同比例Al O(OH)-Si O2的聚酰亚胺杂化薄膜.利用原子力显微镜、热失重分析、介电谱和击穿试验对其表观形貌和热性能、电性能进行表征和测试,考察结构与性能之间的关系.Using polyimide as the matrix resin, polyimide hybrid film with various proportion of AlO（OH）- SiO2 was prepared through the sol- gel reaction of polyimide after the hydrolysis condensation reac-tion of traethoxysilane （TEOS） and heteropropyl- aluminium. The surface morphology, thermal property and electrical property of the film were characterized by atomic force microscope （AFM）, thermal weight loss and dielectric spectroscope and break down test, and the relationship between the structures and properties of the films were investigated.
