Description
Summary:The magnesium conducting solid-state polymer electrolyte PE comprising hybrid of poly（vinyl alcohol） （PVA） and magnesium bromide MgBr2, phosphomolbidic acid （PMA） H3PMol204o, and tetraethylene glycol dimethyl ether （TEGDME） as plasticizer and TiO2 anatase as a nano-filler is prepared at various compositions by solution cast technique. The interactions between the filler and PE chains are studied by thermal gravimetric analysis （TGA）, X-ray diffraction （XRD）, scanning electron microscopy （SEM）, and impedance spectroscopy. Composition of PE is optimized, and maximum conductivity is obtained at 6 wt.% TiO2 anatase. Filler seems to increase the number of free magnesium cations by de-coordinating the bond between magnesium cations and matrix scheme. The estimated value of Mg＋ ion transference number is carried out by the combination of complex impedance and D.C. polarization methods and is found to be 0.52 for the highest conducting film.
