Polycarbonate foil (Makrofol KG, PC) stacks were irradiated with various swift heavy ions (1.158 GeV 56Fe, 1.755 GeV 136Xe and 2.636 GeV 238U) in a very wide electronic stopping power range (from 1.9 to 17.1 keV/nm) and the fluence range from 1×1010 to 3×1012ions/cm2. The amorphous processes and chemical degradation in the irradiated PC were studied by X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy measurements. The results were explained by the thermal spike model.
