The adhesion of polyimide to polyimide was studied by measuring the pe
el strength of various polyimide-polyimide composites. Different facto
rs such as diffusion of polyamic acid to polyimide substrate, contact
angle, wettability, and the thermal expansion coefficient of polyimide
films and the presence of siloxane can affect this adhesion and are d
iscussed in this article. (C) 1994 John Wiley & Sons, Inc.
