Abstract:
A polyimide film is effectively formed on a complicated surface. The polyimide film is formed by reacting, on the surface, diamine monomer and tetracarboxylic acid dianhydride monomer both of which are dissolved within carbon dioxide in a supercritical states, together with a polyamic acid resulting from a reaction between the diamine monomer and the tetracarboxylic acid dianhydride reached to the surface.
