| Abstract: | Silica sol and alumina sol were prepared by sol-gel method.These nano silica and alumina materials were mixed with polyamic acid to prepare the polyimide/ nano-SiO_2Al_2O_3hybrid films.The structure, micro-morphology and thermal properties of the films were characterized by FTIR,SEM and TGA.The results indicated that SiO_2and Al_2O_3particles were well dispersed in PI hybrid films and the chemical bonds between organic and inorganic phase were found.The thermo-decomposed temperature of the films was also increased after appending SiO_2and Al_2O_3particles. |
