COMPOSITE MOLDING OF METAL AND POLYIMIDE

摘要

PURPOSE:To constitute the title composite molding so that it is not deteriorated even not under a specific atomosphere such as a reducing atmosphere by preventing heat deterioration of a polyimide film, by a method wherein an acid functional group such as a carboxyl group or a sulfone group in a polyimide precursor is masked. CONSTITUTION:The title composite molding is manufacture by including a process where a polyimide precursor is imidated by coming into contact with a metal. The polyimide precursor is obtained by masking an acid functional group such as a carboxyl group or a sulfone group of the precursor. In other words, when the metal is dissolved under the existence of carboxylic acid of polyamic acid and then the same is exposed under a high temperature, an imide annulus is pyrolytically decomposed by the metal and at the same time a metal oxide in a particulate state is precipitated away. Then a similar phenomenon to this is observed even on the polyimide precursor having a sulfone acid group and the existence of the acid functional group permits its dissolution is the metal.
