The adhesion and interface structure between copper and polyimide have been studied. Polyimide films were prepared by spinning a polyamic acid solution (Du Pont PMDA-ODA) in an NMP solvent onto a Cu foil, followed by thermal curing up to 400°C. The

The interface and adhesion of PMDA-ODA and PAA-ethyl ester polyimides to several metals including Cr, Ni, Cu, and Au have been studied by transmission electron microscopy (TEM) and a 90° peel test. The adhesion strength of polyimide on metals is gen

Jagged (ball–milled) glass particles were spheroidized and pressed into compacts which were isothermally sintered in air. Both jagged- and spheroidized-particle compacts showed about the same 0.7 anisotropy of the ratio of axial to diametral shrink
