磺化聚芳醚酮砜/ZrO2复合型质子交换膜的制备与性能
Preparation and Behavior of Sulfonated Poly (arylene ether ketone sulfone) s/ZrO2 Composite Proton Exchange Membranes
摘要
Abstract
Sulfonated poly(aryle ether ketone sulfone) ( SPAEKS )/ZrO2 composite membranes with different contents of ZrO2 were prepared by sol-blend mixed method. Infrared spectra show that the Zr-O-Zr absorption peaks exist in composite membrane. SEM images show ZrO2 nano-inorganic particles uniformly dispersed in SPAEKS polymer matrix. It was found that the introduction of nano-particles ZrO2 improved the thermal stability, water uptake and proton conductivity. The methanol permeability coefficient (5. 6 × 10-7cm2/s) of SPAEKS/ZrO2-10% composite membrane was lower than that of SPAEKS film(6.7 × 10-7 cmVs) at 80 ℃ The proton conductivities of all composite membrane exceeded 0.08 S/cm at 80℃, which meet with the requirement of proton exchange membrane fuel cell(PEMFC) at elevated temperature operation. The SPAEKS/ ZrO2 composite membranes show good potential for the usage in high temperature PEMFC.关键词
