Abstract
A method for treating a polyimide surface which includes the steps of amine-treating the polyimide surface and drying the thusly amine-treated polyimide surface. The amine-treating step is preferably carried out by immersing the polyimide in an amine solution which includes an amine and a solvent. The amine is preferably an aliphatic, aromatic, or siloxane amine. The drying step is preferably carried out a temperature of about 50.degree.-200.degree. C. The polyimide is preferably a polyimide having at least one imide functional group in its main chain, and is most preferably a polycondensate of at least one dianhydride and at least one diamine.
