Abstract: The principle and progress of preparation of conductive polyimide composites with in-situ polymerization method, solution blending method, metalized surface modification method and ion implantation method are introduced. The performance of conductive filler of nano metal particles,carbonaceous material and structural conductive polymer are summarized, also with the current research situation. The application of conductive polyimide composites in microwave, electromagnetic shielding,electrostatic dispersion, integrated circuit, conductive film and coatings are briefly described.

Key words: polyimide （PI）, conductive composites, conductive filler
