Polyimide is an extremely important high temperature resistant polymer with excellent heat resist-ance and oxidation resistance, and also has excellent physical and mechanical properties, flame retardant proper-ties, dielectric properties, insulation and radiation resistance. In this paper, the preparation of polyimide using iso-cyanate method was summarized, and the applications of the polyimide in foams, nanocomposites, aerogels, aero-gels and membranes were introduced in detail.
