| Abstract: | Polyimide have been extensively employed in electrical and microelectronics industries as well as aerospace and aviation industries as advanced packaging and insulating materials owing to their outstanding combined mechanical properties, thermal stabilities and electrical insulating properties. With the rapid development of advanced industry, polyimide films with high property and unique function are usually required. Therefore, researches have been done to improve the properties of polyimide film by introducing different inorganic particles. MMT/ PI hybrid films were prepared by incorporation with different content of MMT via an in-situ intercalationpoly- merization pathway. The XRD and TEM results indicated that the silicates are homogeneously dispersed as exfoliated layers in the PI hybrid film with 2% of silicate content. The electrical aging performance of PI hybrid film could also be improved as the silicate layer highly dispersed in the film. |
