Abstract: The modification of chemical cross-linking is an effective method to enhance the anion exchange membrane mechanical properties.The organic superbase pentamethylguanidine (PMG) was used as a functional reagent，and reacted with poly (aryl ether oxadiazole)s to prepare anion exchange membranes (FPAEO-AEMs).The results show that crosslinker 6F-BPA is 6%，and the swelling rate of 28.8%; water absorption of 86.27%; conductivity of 3.12 × 10^-2 S·cm^-1; ion exchange capacity (IEC) of 2.57 mequiv·g^-1; thermal decomposition temperature of up to 280℃.

摘要： 化学交联改性是提高阴离子交换膜机械性能的有效方法。采用有机强碱五甲基胍（PMG）作为功能化试剂，对氟化聚芳醚噁二唑（FPAEO）进行了功能化反应，加入六氟双酚A（6F-BPA）进行化学交联改性处理制得交联型氟化聚芳醚噁二唑阴离子交换膜(FPAEO-AEMs)。分析结果表明：交联剂6F-BPA为6%时，溶胀率为28.8%；吸水率为86.27%；电导率达到3.12×10^-2 S·cm^-1；离子交换容量（IEC）为2.57 mequiv·g^-1；热分解温度可达280℃。
