Abstract:
A micro interface between a polymeric layer and a metal layer for providing mechanical adhesion between the polymeric layer and the metal layer, said micro interface being formed by portions of the polymeric layer and the metal layer and consisting essentially of:isolated clusters of metal atoms gathered together, the isolated clusters being partially embedded in but not diffused into the polymeric layer to mechanically interlock so that a cross section, taken parallel to the micro interface, of an exposed portion of an individual cluster is smaller than a cross section, taken parallel to the micro interface, of an embedded portion of the individual cluster, said isolated clusters forming a portion of the metal layer; and a continuous layer of metal bonded to said exposed portions of said isolated clusters, said continuous layer of metal completing the metal layer.
