The present invention is a method for the modification of the surfaces of polymeric materials with polymer coatings that may be subsequently treated to be lubricious and anti-microbial. The method comprises incubating a photo- initiator-coated polymeric material with an aqueous monomer that is capable of free radical polymerization and exposing the incubating polymeric material to UV light creating a modified surface on said polymeric material. The method may additionally comprise adding a silver component to the modified surface. The silver component may be provided as a silver salt coating or a silver salt contained within a hydrogel bonded to the acrylate modified polymeric material surface.

L'invention porte sur un procédé de modification de la surface de matériaux polymériques à l'aide de revêtements de polymères, traités ultérieurement pour devenir lubrifiants et antimicrobiens. Ledit procédé consiste à incuber un matériau polymérique revêtu d'un photoinitiateur avec un monomère aqueux susceptible de subir une polymérisation des radicaux libres, puis à exposer ledit matériau à l'UV de manière à en modifier la surface. On peut également ajouter à la surface modifiée un composant d'argent sous forme d'un revêtement de sel d'argent ou de sel d'argent présent dans un hydrogel se fixant à la surface du matériau polymérique acrylique modifié.
