Abstract
Applicants' invention is a method for creating an interpenetrating network on the surface of devices and supplies that is biocompatible and antimicrobial.

The quaternary salt in solvent is absorbed by the polymeric substrate and the quaternary salt is polymerized such that an interpenetrating network is formed with said polymeric substrate.
