Abstract: X-Ray Photoelectron Spectroscopy (XPS) has been employed to determine the effect on a biomedical polyurethane, following plasma treatment._2 and Ar irradiation show addition of oxygen containing species, whilst N_2 suggests an etching mechanism. Storage in air results in loss of some introduced groups but not total regeneration of material properties.
