原始语种摘要: A composite polymer electrolyte comprising poly(vinyl alcohol)–poly(4-styrenesulphonic acid) with barium chloride dihydrate ( \(\hbox {BaCl}_{2}{\cdot } 2\hbox {H}_{2}\hbox {O}\) ) salt complex has been synthesized following the usual solution casting. The ionic conductivity of polymer electrolyte was analysed by impedance spectroscopy. The highest room temperature (at 30 \({^{\circ }}\) C) conductivity evaluated was 9.38 \(\times \) 10 \(^{-6}\) S cm \(^{-1}\) for 20 wt% loading of \(\hbox {BaCl}_{2}\) in the polymer electrolyte. This has been referred to as the optimum conducting composition. The temperature-dependent ionic conductivity of the polymer electrolyte exhibits the Arrhenius relationship, which represents the hopping of ions in polymer composites. Cation and anion diffusion...
