| 摘 要： | Nafion® / TiO2 composite membranes were prepared by in-situ chemical reaction method using
Ti(OC4H9)4 and Nafion® 117 as raw materials. The membranes were characterized by UV, FTIR-ATR and XRD, respectively. Methanol permeability and water uptake were investigated as a function of
TiO2 contents. The conductivity of the membranes was measured under water vapor pressure (2.644 7 kPa) or in dry atmospheres. The XRD results showed that the titanium dioxide in Nafion® membranes were crystallized in anatase phase with an average crystaline diameter of 3.0 nm. The water uptake of the composite membranes was larger than that of the pure Nafion® membrane when the
TiO2 loading was within 14wt%. The methanol permeability of the membrane decreased as the
TiO2 loading increased. The addition of 3wt% TiO2 to Nafion® membranes improved the conductivity in dry measurement conditions. The proton conductivity of the composite membrane increased greatly after the hydrothermal treatment at 160 ℃ for 2 hours.
