摘要：

为了满足新能源电池对质子选择性导电膜的需要，提出一种质子传导膜的新型制备工艺，并进行质子传导膜的制备工艺放大。以聚偏氟乙烯（PVDF）和烯丙基磺酸钠（SAS）为原料，成功制备长1000mm、宽800mm的质子传导膜。膜性能测试结果显示，质子传导膜电导率随SAS质量分数变化显著。当SAS质量分数为20%时，膜电导率；膜化学稳定性良好，使用Fenton试剂氧化法测得膜剩余质量百分数97.5%；屈服强度23N/mm2，膜爆破强度为2MPa；TGA分析膜分解温度高于400℃。该膜应用于全钒液流电池，自放电实验测得开路电压下降速率为，库伦效率93%。研究结果表明膜材料综合性能良好，有望在全钒液流电池产业化过程中得到大规模应用。

This study proposed a novel approach to manufacture proton conductive membranes to meet the requirement of developing battery technology for renewable energy storage. Using polyvinylidene fluoride(PVDF) and sodium methyl allylsulfonate(SAS), a membrane of 1000mm×800mm(Length ×Width)was successfully prepared. Its conductivity apparently changed with SAS composition. When SAS’s mass fraction was 20%, the membrane conductivity reached . Moreover, the membranes are of advanced performance in chemical resistance and mechanical stability, remaining 97.5% of sample weight after treated in Fenton solution, bursting strength of 2.0MPa, yield strength of 23N/mm2 and thermal degeneration temperature above 400℃. The test of flow battery showed a self-discharge rate of , columbic efficiency of 93%. The membrane had an overall good performance as a promising separator for the commercialization of vanadium redox flow battery (VRB).
