Abstract:
A laminate comprising:a substrate comprising a polymeric film or a relaxed elastomeric material; and a polymeric coating disposed on the substrate over substantially all of the topographical surface area of the laminate and comprising an ionic surface and one or more layers; wherein at least one layer comprises at least one polymer made from 2-vinylpyridine, 3-vinylpyridine, 4-vinylpyridine, (3-acrylamidopropyl)trimethylammonium chloride, 2-diethylaminoethyl acrylate, 2-diethylaminoethyl methacrylate, 3-dimethylaminopropyl acrylate, 3-dimethylaminopropyl methacrylate, 2-aminoethyl methacrylate, dimethylaminoethyl acrylate, dimethylaminoethyl methacrylate, 2-acryloxyethyltrimethylammonium chloride, diallyldimethylammonium chloride, 2-methacryloxyethyltrimethylammonium chloride, 3-methacryloxy-2-hydroxypropyltrimethylammonium chloride, 3-aminopropylmethacrylamide, dimethylaminoethyl methacrylamide, dimethylaminopropyl acrylamide, 4-vinylbenzyltrimethylammonium chloride, 4-vinyl-1-methylpyridinium bromide, lysine, allylamine, vinylamine, nylons, chitosan, or any combination thereof, and wherein the laminate has a projected surface area and a topographical surface area wherein the topographical surface area is at least about five times greater than the projected surface area.
