以氨化聚砜(APSF)和废弃的Nafion为原料,通过交混流涎的方法制得APSF/rNafion复合膜.采用了扫描电子电镜、拉力测试仪、电化学工作站和充放电测试仪等仪器对复合膜的形貌、力学性能和电化学性能进行表征.结果表明:APSF与rNafion具有很好的兼容性,使得复合膜具有好的力学性能和钒离子选择性.与空白的重铸Nafion膜相比,在不同电流密度下,APSF/rNafion复合膜表现出了突出的电化学性能,同时在40 mA/cm2的电流密度下,复合膜的库伦效率(80 μm,CE=96%)高于商用的 Nafion115的库伦效率(125 μm,CE=94.4%).此外,在80 mA/cm2的电流密度下,用APSF/rNafion复合膜组装的电池经过100圈的循环测试后,仍然具有8...

The APSF/rNafion composite membranes, with the ammoniated PSF and used Nafion as material, were fabricated with blending and casting methods. Some instruments such as scanning electron microscope, tensile testing instrument, electrochemical workstation and charge-discharge tester and so on, were applied to characterize the morphology, mechanical properties and electrochemical properties of the composite membranes. The result showed that APSF had a good compatibility with Nafion, which made the mechanical properties of APSF/rNafion composite mem...
