借助引发剂过硫酸钾(KPS),采用原位聚合法将苯乙烯(St)与Gemini型阳离子分子顺丁烯二酸二乙酯撑基双[辛烷基二甲基氯/溴化铵](G8-2-8)在季铵化壳聚糖(QCS)的醋酸溶液中,引发聚合形成不同嵌段比例(St与G8-2-8的摩尔比)的嵌段聚合物.然后利用戊二醛(GA)为交联剂将QCS交联形成网状结构,将上述线性嵌段聚合物“锁定”在交联的QCS网状结构中,制备了一系列具有半互穿网络结构(Semi-IPN)的阴离子导电膜.性能测试的结果表明,该系列膜具有较高的机械性能和电导率.当G8-2-8含量为QCS质量的20％,嵌段比例为5:1时,表现出最高的离子交换量(1.35 mmol/g),断裂伸长率(26.47％)和电导率(70℃,6.97×10-2 S/cm).热稳定性测定结果表明,该膜具有良好的热稳定性能,最低分解温度高于210℃.
