✦ Synopsis

The grafting of a polyethylene (PE) surface layer implanted with 156 keV Xe ϩ ions at fluences of 3.10 13 to 1.10 15 cm Ϫ2 with alanine was studied with the aim to prepare prospective materials for biological experiments. It was shown by different spectroscopical methods that alanine adds onto double bonds or reacts with radicals created by ion irradiation on the polymer chain. The grafting occurs in the whole ion-damaged polymer layer.

Pulse ion beam treatment was employed for polyethylene (PE) surface modification. Ultraviolet, infrared (IR), IR-attenuated total reflection spectroscopy (IR-ATR), and X-ray photoelectron spectroscopy methods, as well as wetting angle measurement, were used for the analysis of PE structural changes.
