Electrical Conductivity Effect for Grafted Polystyrene at Different Grafting and Gamma Dose

Grafted polystyrene with acrylonitrile using gamma-irradiation was studied the electrical current (I), electric field strength (E), at different ionic jump distance (a) and room temperature (T). The gamma-irradiation dose, acrylonitrile percentage (as a monomer), ferrous ammonium sulphate (FAS) percentage (as a catalyst) and grafting percentage on the electrical conductivity were studied. It was found that the electric current increases 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 polystyrene with out grafting and with grafting were studied. Effect of temperature on the redox process of K^sub 3^Fe(CN)^sub 6^ was studied on grafted polymer by cyclic voltammetry using Arrhenious equations. The new grafted polymer has high redox stability and is considered to belong to the most useful conductive grafted polymer for practical application. Copyright © 2012 IFSA.
