Document Type and Number:
WIPO Patent Application WO/2016/159061
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a polyimide film containing fluororesin particles, the method providing excellent productivity and high peeling strength to the polyimide film when the film and a metal foil or the like are bonded together with an adhesive layer therebetween. The present invention uses a method for disintegrating agglomerated fluororesin particles by means of a shear force without using a dispersant, which could cause defects, and without crushing the fluororesin particles. Furthermore, thermal and chemical imidization methods are used in combination to disperse the fluororesin particles.
