摘要

A new class of polyimide hybrid films with various amounts of silica and alumina has been synthesized by the sol-gel reaction and characterized. The hybrid films were obtained by the hydrolysis and polycondensation of heteropropyl-alumina and tetraethoxysilane (TEOS) in a polyamic acid (PAA) solution of N,N'-dimethylacetamide (DMAc), followed by heating to 350/spl deg/C. The chemical structure and surface morphology of the composites films were characterized by Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). The thermal stability of the composite films was tested on a Perkin-Elmer TGA7. Thermal stability of the hybrid film was increased with the nano scale inorganic oxides. The presence of silica and alumina has a significant effect on the properties of polyimide films.
