合成了由交联聚乙烯醇和季铵化聚乙烯基苄基氯组成的互穿聚合物网络阴离子交换膜。电子显微镜清晰地揭示了IPN结构，并通过这种结构设计，在IPN AEMs中构建了高效的离子通道。这种特殊设计的结构导致高氢氧化物（OH-）电导率（例如，141.7 mS cm− 1（80 °C时），中等离子交换容量（IEC）为1.61 mmol g−1，在H2/空气（无CO2）阴离子交换膜燃料电池（AEMFC）测试中使用非贵金属氧还原反应（ORR）催化剂时，峰值功率密度为0.64 W cm− 2。
Interpenetrating polymer network anion exchange membrane (IPN AEM) consists of cross-linked quaternized poly (vinylbenzyl chloride) and cross-linked poly (vinyl alcohol) is synthesized in this work. Electron microscope clearly reveals the IPN structure, and with this structural design, a highly efficient ion channel within IPN AEMs is constructed. This specially designed structure leads to high hydroxide (OH−) conductivity (e.g., 141.7 mS cm−1at 80 °C) at a moderate ion exchange capacity (IEC) of 1.61 mmol g−1, and a remarkable peak power density of 0.64 W cm−2with non-noble metal oxygen reduction reaction (ORR) catalyst in H2/Air (CO2-free) anion exchange membrane fuel cells (AEMFCs) test.
