Popis: | An attempt has been made in the present work to develop blend based mixed ion-electron conductor viz. PVA: PVK: CH3COONH4: EC system. Formation of polymer blend and composite has been evidenced during XRD and IR studies. Ionic conductivity of this system is seen to improve by an order of magnitude at room temperature with optimum at 1.27×10-3 S/cm for 0.4 mole ammonium acetate concentration. Ionic charge transport seems to dominate as reflected from I-t measurements. Temperature dependent conductivity shows that ionic conduction is controlled by combination of Arrhenius and VTF behavior. AC conductivity behavior is seen to be dictated by Jonscher Power law. |
