<p>PURPOSE:To obtain easily a polyimide molding having a surface with excellent adhesive properties, by treating the surface of the molding with a basic compd. and then with a silane coupling agent and heat-treating it. CONSTITUTION:The surface of a polyimide molding such as a polyimide film, a polyimide laminate, etc. is treated with a soln. contg. a basic compd. (e.g., sodium hydroxide, tetramethylammonium hydroxide) and then with a silane coupling agent (e.g., gamma-mercaptopropyltrimethoxysilane, gamma- aminopropyltriethoxysilane), e.g., by immersing it therein. The product is heat- treated at 80 deg.C or higher to improve the adhesion of the surface of the molding.</p> |
