Patent

CA 2316214

Applicants' invention is a method for creating an interpenetrating network on the surface of devices and supplies that is biocompatible and antimicrobial. According to Applicants' invention, a polymerizable or 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 such that an interpenetrating network is formed with said polymeric substrate.

L'invention se rapporte à un procédé de création d'un réseau enchevêtré, biocompatible et antimicrobien, à la surface de dispositifs ou de denrées. Ce procédé consiste à exposer un substrat polymère à un sel d'ammonium quaternaire monomère ou polymérisable présent dans un solvant. Ledit sel quaternaire du solvant est absorbé par le substrat polymère, il est polymérisé et forme avec le substrat polymère un réseau enchevêtré.
