First Claim
Patent Images
1. A method for modifying the surface characteristics of a solid polymeric material comprising the steps of;
- (a) irradiating a surface of the polymeric material in the presence of an oxygen source such that the bulk properties of the material are not degraded;
(b) applying to the irradiated surface an aqueous solution including acrylamide monomer and ceric ion, whereby the monomer is grafted to the irradiated surface.

Abstract
A method for modifying the surface characteristics of a polymeric material by irradiating a surface of the polymeric material in the presence of an oxygen and then grafting acrylamide to the irradiated surface by contacting the irradiated surface with an aqueous solution including acrylamide monomer and ceric ion. Grafted polymer surfaces with dense surface coverage are produced without using a deaerated monomer solution. Biofunctional molecules can be ionically or covalently bonded to the grafted surface.
