Beschreibung
Zusammenfassung:	A method for modifying the surface characteristics of a polymeric material by irradiating a surface of the polymeric material in the presence of 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.
