Abstract: Polyimide/TiO2 composite films were prepared via sol-gel reaction using tetrabutyl titanate (TBT) as the inorganic precursor and incorporating it into poly (amic acid) (PAA) derived from 3,3',4,4'-biphenyl tetracarboxylic diandhydride (BPDA)and 4,4'-diaminodiphenyl ether (ODA) in N,N-dimethylacetamide (DMAc). The chemical structure and compatibility of the hybrid film were characterized by FFIR and SEM, respectively. The effect of TiO2 content on mechanical property and thermal behavior of hybrid film was studied. The results indicated that the nano TiO2 particles dispersed uniformly in polyimide matrix. And the comprehensive properties were optimal when the content of TiO2 is about 2wt.%.
