Patent number: 11949137Abstract: The present invention belongs to the field of alkaline polymer electrolyte membranes, and relates to a comb-shaped structure polybenzimidazole anion exchange membrane with high conductivity and preparation method thereof. In the invention, firstly, polybenzimidazole is grafted with the non-cationic side chains to the max grafting rate to synthesize the de-protonated comb-shaped polybenzimidazole material, avoiding the N—H in benzimidazole forms ionic binding with cationic functional groups, which will reduce the reactivity and mobility of cationic groups; then react de-protonated comb-shaped polybenzimidazole with quaternization reagent to attach the pendent side chain with cationic functional groups, making it easy to aggregate to form ion clusters and hydrophilic/hydrophobic microphase separation. The anion exchange membrane prepared in this invention has excellent conductivity, mechanical properties and alkaline stability.Type: GrantFiled: March 19, 2020Date of Patent: April 2, 2024Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Xuemei Wu, Gaohong He, Xiaozhou Wang, Xiaoming Yan, Tiantian Li, Wanting Chen, Xiangcun Li, Wu Xiao, Xiaobin Jiang, Fujun Cui, Yan Dai, Xuehua Ruan
