Characterization of SiO2-P2O5-ZrO2 Sol-Gel/NAFION™ Composite Membranes
Source abstract
Abstract
Composite membranes were prepared by (a) infiltrating NAFION™ with SiO2-P2O5-ZrO2 sol, and (b) recasting a film using NAFION™ solution containing SiO2-P2O5-ZrO2 sol. The membranes were characterized by Differential Thermal Analysis and ac-impedance spectroscopy as a function of relative humidity. The influences of the heat treatment (80°C–150°C) and cleaning on the electrical properties were investigated. The incorporation of SiO2-P2O5-ZrO2 gels into NAFION™ lead to improvements in its thermal stability and proton conductivity.
