Abstract

High temperature protonic conducting polymer membranes provide new technological applications in the electrochemical devices including electrochromic displays, chemical sensors, fuel cells and others. Organic/inorganic nanocomposites membranes, consisting of SiO2/PEO (Polyethylene Oxides) hybrids, are a remarkable family of isotropic, amorphous polymer materials, which have been synthesized through sol-gel processes. The hybrid membrane doped with acidic surfactant molecules shows good protonic conductivities at high temperatures above 100°C. The membrane was found to be thermally stable at high temperatures because of the inorganic SiO2 framework in the composites matrix.
