Abstract

Polymer electrolytes based on ammonium fluoride (NH₄F) and poly (vinylidene fluoride-co-hexafluoropropylene) (PVdF- HFP) have been prepared by solution casting technique using Tetrahydrofuran (THF) as a solvent and characterized by complex impedance spectroscopy. Maximum conductivity of 2.17x10^-7 S/cm at room temperature has been obtained for polymer electrolytes PVdF-HFP+10wt%NH₄F. The effect of different plasticizers Propylene Carbonate (PC), Dimethylformamide (DMF) and Dimethylacetamide (DMA) on conductivity behavior has been studied. It has been found that, the conductivity of polymer electrolytes increases by three orders of magnitude from 10^-7 to 10^-4 S/cm with the addition of plasticizers. Maximum room temperature conductivity of 8.8x10^-6 S/cm, 7.8x10^-5 S/cm and 1.1x10^-4 S/cm has been observed for plasticized polymer electrolytes containing PVdF-HFP+30 wt% NH₄F and 95 wt% PC, DMF, DMA respectively, which can be explained on the basis of donor numbers of plasticizers used. The addition of plasticizer to polymer electrolytes has been observed to decrease in glass transition temperature (T_g ). The variation of conductivity with temperature suggests that, these polymer electrolytes are thermally stable and small change in conductivity with temperature is suitable for their use in practical applications like solid state batteries, fuel cells, electro chromic devices, super capacitors, etc.
