Abstract:
A method for making a modified surface on a polymeric material, the method comprising:incubating a photo-initiator-coated silicone material provided as a device selected from the group consisting of implants, catheters, stents, wound dressings, cardiac valves, tubings, pins and clips with an aqueous monomer solution capable of free radical polymerization and selected from the group consisting of acrylic acid, methacrylic acid, 2-carboxyethyl acrylate, 4-vinylbenzoic acid, itaconic acid, and mixtures thereof, wherein the photo-initiator Is selected from the group consisting of p-benzoyl tert-butylperbenzoate, 2,2-dimethoxy-2-phenyl-acetophenone, benzil ketals, benzoins and their derivatives and mixtures thereof; exposing the incubating material to ultraviolet (UV) light creating a modified surface on said material; washing and drying said material with said modified surface.
