An 8MeV electron-induced modification of Lexan polycarbonate (Lexan) films has been studied systematically using UV-visible spectroscopy, LCR meter, X-ray diffractogram (XRD) and differential scanning calorimetry (DSC) techniques. The optical properties of the Lexan films showed a decrease in the optical energy gap with an increase in the electron dose. The AC conductivity and dielectric constant were found to change significantly due to irradiation, and the dielectric constant was found to obey the universal law of dielectric constant. The XRD results show that the crystallite size and the percentage of crystallinity of films decrease after irradiation. The decrease in glass transition temperature shown by DSC studies reveals that the polymeric system has changed towards a more disordered state.
