Abstract

Investigations regarding mechanisms involved in surface modification of PET films subjected to the action of oxygen ions of relative low energies (100-500 eV) were realized. PET films of 25 biaxially drawing were concomitantly exposed to the action of positive ion beam delivered by a Kaufman ion source and to dilute target plasma. X-ray photoelectron spectroscopy (XPS) measurements at different take off photoelectron angles (sampling depth x) were performed on ESCALAB Mk II. Theoretical model that describes atomic mixing and erosion in the case of PET samples exposed to positive low energy ions has been obtained on the bases of the models developed by Sigmund Grass-Mari and Collins..
