1. A method for immobilizing anti-microbial compounds onto an elastomeric surface, the method comprises:
- a) providing substrate having a surface with either polar or non-polar functionality;
b) providing at least a layer of molecules, said molecules having at least bi-functional polar character selected from hydroxyl, amine, amides, imine, imide, carbonyl, carboxyl, ester, aldehyde, or ether groups, in which at least one portion of said molecules has a reactive oxygen or nitrogen group exposed, and applying to said layer an anti-microbial agent having a functional group reactive with said exposed oxygen group.

Abstract
A method for modifying the surface chemistry of an elastomeric substrate and articles embodying the substrate is described. The method involves pre-treating the substrate surface to create active oxygen groups on the substrate for immobilizing securely an antimicrobial agent to the substrate. The active oxygen groups can react and bind with functional groups of the antimicrobial molecules according to predetermined orientation to enhance biocide reactivity.
