The main objective of this study is to determine the dielectric constant (εr) of UV–radiation irradiated pure PS (polystyrene), pure PVAc (poly vinyl acetate) and Polyblends of PS-PVAc at varying temperature and also at the different frequencies (1 KHz to 1MHz) using 4284 LCR source meter. It is found that the dielectric constant varies with the temperature of pure and blends. From the results, it was also attributed that as these polymer thin films are exposed to UV radiation, their dielectric constant varies with temperature. |
