以聚乙烯醇(PVA)、聚苯乙烯磺酸(PSSA)和钠基蒙脱土(Na-MMT)为原料,戊二醛(GA)为交联剂,通过溶液共混法制备交联型PVA/PSSA/Na-MMT质子交换复合膜.红外光谱(IR)分析表明,复合膜中PSSA的磺酸基与PVA的羟基发生酯化交联反应,提高了复合膜的稳定性;热重分析(TGA)证明,复合膜具有较好的耐热性;扫描电镜(SEM)显示,MMT在复合膜得到均匀的分散.交联剂戊二醛(GA)和钠基蒙脱土(Na-MMT)提高了复合膜的耐水性与尺寸稳定性.含有质量分数15％PSSA和3％Na-MMT复合膜的钒离子渗透率为1.58×10-6 cm2/min.单电池的库伦效率可达43.7％.
