Abstract

In the present paper, a kind of polyimide/silica/alumina hybrid films based on 4,4´-oxydianiline (ODA) and pyromellitic dianhydride (PMDA) was prepared through sol-gel reaction by the hydrolysis and condensation of methyltriethoxysilane (MTEOS) and heteropropyl aluminum in the polyamic acid (PAA) solution of N, N-dimethylacetamide (DMAc). The chemical structure of the films, characterized by FT-IR, indicated that the imidization reaction was complete. The results of TGA proved that the thermal stability can be improved by well dispersion of adequate addition of silica and alumina
