Hydrogen profile in ion implanted polyethylene

Abstract
Change of the hydrogen concentration induced by ion irradiation in the polyethylene films has been studied by MeV proton backscattering. Ion implantation of polyethylene film results in a strong breakup of chemical bonds in the chains with a large hydrogen emission leaving a carbon enriched film.These effects are confined in a cylinder around the ion track, of cross section 1015 cm2 and a length comparable with the ion range.
