Modifications induced in the polycarbonate Makrofol KG polymer by Li (50 MeV) ion irradiation

摘要

Swift heavy ions interact predominantly through inelastic scattering while traversing any polymer medium and produce excited/ionized atoms. Here samples of the polycarbonate Makrofol of approximate thickness 20 fan, spin coated on GaAs substrate were irradiated with 50 MeV Li ion (+3 charge state). Build-in modifications due to irradiation were studied using FTIR and XRD characterizations. Considerable changes have been observed in the polymer while varying the fluence from 1E11 ion/cm~2 to 1E13 ion/cm~2 Li ions. AFM images of the surface modifications caused by ion irradiation on the polymer are also presented.
