To provide a new material exhibiting a new function by using a polyimide film having excellent heat resistance, chemical resistance and mechanical strength as a base material; and to provide a proton conductive film having heat resistance and proton conductive properties by using the polyimide film as a base material.
The polyimide porous film composite material is obtained by filling the pores of a polyimide porous film with a highly heat-resistant organic material and/or an inorganic material to keep the shape by the physical and/or chemical interaction. The proton conductive film is obtained by filling the pores of the polyimide porous film with a monomer or macromonomer becoming a precursor of a polymer having high heat resistance and proton-conductive properties, and inducing a chemical reaction such as macromolecularization and crosslinking to form the polymer.
