Abstract In contrast to typical grafted anion exchange membranes (AEMs), a novel graft type AEM owning flurocarbon side chains and quaternized ammonium aromatic backbone was developed by a controlled atom transfer radical polymerization (ATRP) reaction. The experimental results revealed this kind of structure facilitated the formation of robust and long connective ion transport channels. Thus, the resulting AEM (IEC = 1.35 mmol/g) exhibited a relatively high hydroxide conductivity of 44 mS/cm, although its water uptake was below 30% (at 30 °C). Simultaneously, this AEM also displayed fascinating mechanical strength and alkaline stability. A H 2 /O 2 fuel cell test using incorporated fluorocarbon grafted AEMs yielded a peak power density of 85 mW/cm 2 at a current density of 150 mA/cm 2 ; this will be improved on development of a chemical compatible fluorine-based alkaline ionomer as ionic polymer binder in the electrodes' catalyst layers.

一种通过碳氟化合物接枝聚合物构建高导电性和稳定阴离子通道的新策略

摘要 与典型的接枝阴离子交换膜 (AEM) 不同，通过可控原子转移自由基聚合 (ATRP) 反应开发了一种具有氟碳侧链和季铵化芳族主链的新型接枝型 AEM。实验结果表明，这种结构有助于形成坚固而长的连接离子传输通道。因此，所得的 AEM (IEC = 1.35 mmol/g) 表现出相对较高的氢氧化物电导率，为 44 mS/cm，尽管其吸水率低于 30%（在 30°C 下）。同时，这种 AEM 还显示出迷人的机械强度和碱稳定性。AH 2 /O 2 燃料电池测试使用掺入的碳氟化合物接枝AEM，在150 mA/cm 2 的电流密度下产生了85 mW/cm 2 的峰值功率密度；
