Structural and electroactive properties of 55 MeV carbon ion beam irradiated polycarbonate films

Semicrystalline polycarbonate thin films have been prepared by solvent casting method and irradiated by 55 MeV carbon ion beam under vacuum at room temperature with various ion fluences. The Electro active properties of the ion beam irradiated films were illustrated by means of UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermally stimulated discharge current (TSDC), For XRD we conclude that the effect of carbon beam irradiation on polycarbonate film that crystallite size in polycarbonate is decreased. For UV–Visible absorption spectra show that the energy band gap of polycarbonate decreases with ion fluences. The FTIR spectra of carbon ion beam irradiated polycarbonate film shows the cross linking and chain scissoring was observed. TSDC shows that activation energy, released charge, α-relaxation peak, and charge carrier mobility decrease while relaxation time and peak current increases with ion fluences.
