摘要：

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了交联型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，提高了的复合膜的稳定性，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15%PSSA和3%Na-MMT复合膜的钒离子渗透率为1.58×10-6 / cm2•min-1。单电池的库伦效率可达43.7%。

Cross-linked PVA/PSSA/Na-MMT (poly(vinyl alcohol) /poly(styrene sulfonic acid) /Na-montmorillonite) composite proton exchange membranes were prepared by blending PVA, PSSA and MMT in solution using GA as crosslinking agent. Infrared spectrum (IR) proves that PVA cross-linked with PSSA by esterification between sulfonic acid groups and hydroxyl groups. Thermal gravimetric analysis (TGA) shows the composite membrane has good thermal resistance. The MMT has been uniformly dispersed in the composite membrane observed by scanning electron microscopy (SEM). The glutaraldehyde (GA) and Na-montmorillonite ( Na-MMT) lower water uptake and improve dimensional stability for the composite membranes. Permeability of VO2+ of blend membrane which contains 15%PSSA and 3%Na-MMT achieve 1.58×10-6 / cm2•min-1. The coulombic efficiency of single VRB reaches 43.7%.
