Abstract :
In this paper, a new type of PI/SiO2-Al2O3 hybrid film was prepared by sol-gel method. The effects of ¿ -aminopropyl triethoxysilane(DB-550) were studied as follows: the micro-morphology of inorganic phase of the films was characterized by Atomic force microscope (AFM); the thermal property of hybrid films was measured by thermogravimetric analysis (TGA); and the breakdown strength was got from breakdown strength apparatus. The results indicated that the participation of quantificational coupling agent (DB-550) produced more chemical bonds between inorganic phase and organic phase, which enhanced the compatibility of two phases. The thermo-decomposed temperature and the breakdowm strength of the hybrid films doped coupling agent were all improved.
