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