Abstract:
1. A hydrogel-metal assembly, comprising: an intervening polymer network having bonded together the surfaces of a water-swollen hydrogel layer and a biocompatible, surface-modified metallic layer, wherein said hydrogel layer is an interpenetrating polymer network hydrogel comprising a first network physically entangled with a second network, wherein said first network comprises telechelic macromonomers with diacrylamide as the end groups of said telechelic macromonomers and wherein said second network comprises chemically crosslinked polymers, wherein said intervening polymer network comprises telechelic macromonomers, wherein said biocompatible surface-modified metallic layer is surface-modified with an inorganic material, and wherein said intervening polymer network has been chemically grafted to said inorganic material of said biocompatible surface-modified metallic layer through bi-functional linker molecules, and wherein said intervening polymer is physically or chemically cross-linked with said telechelic macromonomers of said water-swollen hydrogel.
