Q. Dai et Y. Lu, ADHESION PROMOTION FOR EPOXY RESIN COPPER AND POLYIMIDE/COPPER JOINTSBY A 2-COMPONENT COUPLING SYSTEM OF POLY(4-VINYLIMIDAZOLE) AND CYSTAMINE/, Die Angewandte makromolekulare Chemie, 227, 1995, pp. 121-129
A two-component coupling agent layer on copper, produced by immersion
of copper in poly(4-vinylimidazole) solution and then in cystamine sol
ution, showed better anticorrosive performance and higher adhesive str
ength for epoxy resin and polyimide than each single component even at
high temperature.
