Abstract
A composite comprising a substrate and a polymeric coating adhered to at least one surface of said substrate, said polymer coating having a thickness of about 1 to about 100 micrometers, wherein said polymer coating comprises an ionically and covalently crosslinked neutralized carboxylated polymer having a carboxylate content of about 5 to about 300 meq. per 100 grams of said ionically and covalently crosslinked neutralized carboxylated polymer.
