Abstract

Abstract : Polyimide (PI, (C22 H10 O5 N2 )n ) foil, 8 µm thick, was irradiated with 9.6‐MeV C 4+ and O 4+ ions at fluences of 10 10 –10 13 cm −2 . Compositional and structural changes related to the ion species, ion irradiation fluence and the type of polymer were studied and discussed in connection with energy‐loss measurement. The knowledge of these changes of polymers after the irradiation is very important for the estimation of the influence of these effects on the experimentally determined ion‐energy losses. Rutherford back‐scattering (RBS) and elastic recoil detection analysis (ERDA) were used for the elemental composition study, atomic force microscopy (AFM) for the detection of the changes in surface roughness and UV–Visible spectral study (UV–Vis) for variation in the absorbance and the optical band gap. The chemical and structural changes, new radical appearance, and polymeric chain crosslinking especially at ion fluencies above 10 13 cm −2 were observed and discussed in the frame of energy stopping experimental determination.
