Abstract

Composite proton conducting non aqueous polymer gel electrolytes have been synthesized by dispersing nano sized fumed silica to the polymer gel electrolytes containing polymethylmethacrylate (PMMA), dimethylacetamide (DMA), benzoic acid (BA) and ortho-hydroxy benzoic acid (o-OHBA). These electrolytes have been characterized by complex impedance spectroscopy, viscosity and pH measurements. The effect of acid, polymer and fumed silica on conductivity, pH and viscosity has been studied for gel electrolytes. Maximum conductivity of 2.95 x 10-4 S/cm and viscosity of 1.64 x 105 mPas at 25o C has been obtained. The conductivity of composite gels does not show any appreciable change with time and only a small change in conductivity is observed over the operational range of temperature, which is desirable for their use in device applications.
