Wetting modifications of UHMWPE surfaces induced by ion implantation (original) (raw)

Radiation Effects and Defects in Solids, 2003

Abstract

Ultra-high-molecular-weight-polyethylene (UHMWPE) surfaces are characterized in terms of roughness and wetting. Changes in the surface morphology of the polymer were induced macroscopically by mechanical friction and microscopically by ion implantation. The ion irradiation was obtained by using 300 keV Xe+ beams with doses ranging between 10(14) and 10(15) ions/cm(2) . Roughness and wetting measurements were performed in order to investigate
