Degradation of PET, PEEK and PI induced by irradiation with 150 keV Ar~+ and 1.76 MeV He~+ ions

摘要

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 ~4He~+ 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.
