Abstract:

      Polyimide fiber， as an artificial and synthetic polymer， and a current research hotspot， is an important basic raw material for composite materials used in rail transit， aerospace， and defense industry due to its excellent temperature resistance， insulation property， flame resistance， radiation resistance， and high strength & modulus. Herein， the progress in preparation technology of polyimide fiber and polyimide paper-based functional materials in domestic and overseas were reviewed. The technical problems existed in production of polyimide paper-based functional materials were discussed， and the development trend of polyimide and its paper-based functional materials was prospected.
