Abstract
A polyamic acid solution includes a polyamic acid, a solvent (C) in which the polyamic acid (PAA1) is dissolved, and a substance (M) that can release at least one metal selected from groups 1 and 2 of the periodic table as a metal ion, or a substance (m) that contains the substance (M). A polyimide composite is produced from the polyamic acid solution. The polyimide composite can provide a greatly improved glass transition temperature without impairing the intrinsic physical properties of the polyimide.
