US 2026/0048414 A1 · METHOD FOR SURFACE-INITIATED POLYMERIZATION ON SURFACES AND COATED SUBTRATED FORMED THEREBY

Abstract

Methods for applying a polymeric coating to a substrate are provided comprising: (a) generating reactive functional groups on the polymeric substrate; (b) contacting the substrate with a radical polymerization initiator; (c) allowing the polymerization initiator to be chemically bonded to the substrate by reaction of the polymerization initiator with the reactive functional groups on the substrate; (d) contacting the polymerization initiator that is chemically bonded to the substrate with a monomer composition comprising a free-radical polymerizable monomer having at least one hydrophilic functional group; (e) forming a polymeric coating layer on the substrate via a radical polymerization process; and optionally (f) subjecting the polymeric coating layer on the substrate to conditions to effect curing of reactive functional groups on the polymers of the polymeric coating layer. The monomer composition may comprise at least 10 percent by weight of a (meth)acrylamide monomer having at least one ionic functional group.
