Abstract
Protonic conducting polymer membranes provide new technological applications in the electrochemical devices including fuel cell, electrochromic window, chemical sensors and etc. Organic / inorganic membranes are which have been synthesized through sol-gel process isotropic, amorphous.The article reports that PEO molecular weight 600, blending with PWA which can increase ionic conduction can elevate the total ionic conductivity, and blending with Mph which can improve thermal stability may increase the temperature of decomposition. We measure the ion conductivity by Electrochemical Impedance Spectroscopy measurement and fine the best conductivity approach up to 10-4S/cm by blending with 40% PWA. We measure the thermal stability by TG/DTA and find that the temperature of decomposition can approach up to 390℃ by blending with 40% Mph.
