Abstract
Polyethylene terephthalate (PET) films of 50 μm thickness were exposed to swift-heavy 50 MeV copper and 84 MeV oxygen ions, with fluence varying from 1 × 1011 to 1 × 1013 ions cm−2. Differential scanning calorimetry (DSC), X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) and UV-visible spectroscopic techniques were used to characterize the irradiated samples. The XRD and DSC analysis indicated the loss of crystallinity during/after the irradiation. The FTIR spectra revealed the formation of alkyne end groups, CC groups and structural deformation with increase of ion fluence. Considerable reduction in the value of the optical bandgap was inferred from the study of the UV-visible absorption curves.
