摘要: 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℃。
