We incorporate epoxy group functionalized side chain and imidazolium-terminated flexible side chain to norbornene copolymer backbone result in forming a space cross-linked topological structure for alkaline anion exchange membrane (AAEM). The introduction of epoxy groups to the copolymer backbone gives it some special properties, such as good solubility in ordinary organic solvent and the formation of self-cross-linked structure under alkaline environment without additional cross-linker or initiator. The as-prepared copolymers show excellent thermal stability (Td > 320 °C). The self-assembly of hydrophilic flexible side chains and hydrophobic polymer backbone result in well-defined micro-phase separation. The hydroxide conductivity of AAEMs as high as 90 mS cm⁻¹ at 80 °C and after 10 days in 2 M NaOH aqueous at 60 °C the hydroxide conductivities of membranes only decreased by 25%. A peak power density of 118.4 mW cm⁻² at a current density is 253.1 mA cm⁻² is demonstrated.

我们将环氧基官能化的侧链和咪唑鎓封端的柔性侧链结合到降冰片烯共聚物主链上，从而形成用于碱性阴离子交换膜（AAEM）的空间交联拓扑结构。在共聚物主链上引入环氧基团使其具有一些特殊的性能，例如在普通有机溶剂中的良好溶解性，以及在碱性环境下无需额外的交联剂或引发剂即可形成自交联结构。所制备的共聚物显示出优异的热稳定性（Td> 320°C）。亲水性柔性侧链和疏水性聚合物主链的自组装导致定义明确的微相分离。AAEMs的氢氧化物电导率高达90 mS cm ^-1在80°C下，在60°C下的2 M NaOH水溶液中放置10天后，膜的氢氧化物电导率仅降低25％。示出了 在电流密度为253.1mA cm ^-2时的118.4mW cm ^-2的峰值功率密度。
