Abstract: Grafted polystyrene with acrylonitrile using gamma-irradiation was prepared thin film on glass substrate using spray technique. The gamma-irradiation dose and grafting percentage on the electrical conductivity were studied. It was found that the conductivity decreases upon increasing both gamma-irradiation dose and grafting percentage. The ionic jump distances values were calculated and the variation of ionic jump distance with both gamma-irradiation doses and grafting percentage were reported. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) of grafted polymer were studied under electroanalysis in aqueous 0.1 KCl solution. Electrochemical impedance spectroscopy (EIS) of grafted polymer was compared study with conductive electrode.


Keywords: Grafted polymer, Conductivity, Ionic jump distance, Gamma-irradiation
