Abstract
Applicants' invention is a product that is biocompatible and antimicrobial. According to Applicants' invention, a monomeric quaternary ammonium salt in a solvent is exposed to a polymeric substrate. The quaternary salt in solvent is absorbed by the polymeric substrate and the quaternary salt is polymerized thereby creating a product having quaternary salts impregnated on its surface. The polymerized material also penetrates the surface to some depth forming an interpenetrating network.
