  • Abstract

    New solvent-free polymer blend electrolyte thin film specimens consisting of poly (ethylene oxide) (PEO)/polyvinyl pyrrolidine (PVP) were obtained by means of addition of potassium iodide, KI and iodine, I2 and incorporated with pyrazole as the dopant material using solution casting technique. The freshly-prepared films were structurally examined using x-ray diffraction (XRD) analysis 111 as an enhanced ionic conductivity (σ) behavior was characterized by employing complex impedance analysis resulting in 8.46?10-6 Scm-1 at room temperature. The occurrence of complexation of the pyrazole with the chosen polymer blend has been confirmed by the Fourier transform infrared spectroscopy (FTIR) while differential scanning calorimetric (DSC) analysis has suggested the feasibility of complete miscibility of these polymeric systems
