Abstract
The proton conducting polymer blend electrolytes based on poly(vinyledine fluoride):poly(vinyl alcohol) (PVdF:PVA) polymer blend, doped with ammonium acetate (CH3COONH4) in different concentrations, have been prepared by a solution casting technique using dimethyl formamide (DMF) as solvent. The increase in amorphous nature of the polymer electrolytes has been confirmed by X-ray diffraction analysis (XRD). The Fourier transform infrared spectroscopy (FTIR) analysis confirms the complex formation between the polymers and the salt. From the ac impedance spectroscopic analysis, the ionic conductivity of 5 MWt% CH3COONH4-doped PVdF:PVA polymer blend electrolyte has been found to be maximum of 1.30 × 10−6 S/cm at room temperature.
