We acquired herein a novel pendant type anion exchange membrane by grafting brominated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO) with HLTEI (1-(2-(hexylthio)ethyl)-1H-imidazole), a monomer synthesized via click chemistry. The membrane shows improved hydroxide conductivity because of the flexible side chain induced microphase-separated morphology. Low water uptake is the added benefit of the synthesized membrane.
