Abstract
A polyimide-based composite according to the invention is formed using a precursor comprising (A) a polyimide component and (B) another polymer component, wherein the polyimide forms a continuous phase and the other polymer forms a discontinuous phase, and the elastic modulus is less than 10 GPa. This structure provides both the properties of insulation, etc. contributed by the polyimide and the properties of low elastic modulus and satisfactory adhesion, moldability, etc. contributed by the other polymer. The polyimlde-based aqueous dispersion of the invention has dispersed therein particles with a mean particle size of 0.03-5 &mgr;m comprising the precursor of the polyimide-based composite, the dispersed particles including in the same particles the (A) polyimide component and (B) other polymer component comprising a hydrophilic polymer. This gives satisfactory storage stability to the aqueous dispersion.
