✦ Synopsis


In this work, PET was implanted with 150 keV Ar + ions to the fluences of 10 12 -10 15 ions/cm 2 , PET, PEEK and PI with 1.76 MeV 4 He + ions to the fluences 10 13 -10 14 ions/cm 2 . Structural and compositional alterations of the implanted polymers were studied using Rutherford back-scattering (RBS), elastic recoil detection analysis (ERDA), ultra-violet and visible light spectroscopy (UV-VIS) and positron annihilation spectroscopy (PAS). The formation of a new bonds in modified polymer films are detected in proportion to the used ion dose using UV-VIS spectroscopy. For Ar + ions and higher fluences a decline in hydrogen and oxygen content is observed.
