| Abstract: | In this paper,nano silica-alumina/polyimide hybrid films were prepared by sol-gel method.The structure,micro-morphology,thermal properties of the films were characterized by FTIR,SEM and TGA.The results indicated that SiO_2 and Al_2O_3 particles were well dispersed in PI hybrid films and there were chemical bonds between organic and inorganic phase.The thermo-decomposed temperature of the film was also improved after appending SiO_2 and Al_2O_3 particles. |
