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.

L'invention concerne un procédé permettant de modifier la chimie de surface d'un substrat élastomère et d'articles comprenant le substrat. Le procédé consiste à traiter au préalable la surface du substrat, de manière à créer des groupes d'oxygène actif sur le substrat, aux fins d'immobilisation sûre d'un agent anti-microbien sur le substrat. Les groupes d'oxygène actif peuvent réagir avec des groupes fonctionnels des molécules anti-microbiennes et se lier à ceux-ci, selon une orientation prédéterminée, afin d'améliorer la réactivité du biocide.
