A high performance of anion exchange membranes (AEMs) is highly demanded in anion exchange membrane fuel cells (AEMFCs) and has been extensively studied. Therefore, in this study, poly(styrene-b-6-bromohexyl acrylate-b-styrene) was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. Subsequently, the middle block made of poly(6-bromohexyl acrylate) was crosslinked with various diamine crosslinkers to prepare midblock-crosslinked poly(styrene-b-6-bromohexyl acrylate-b-styrene) as AEMs. Various characterizations were performed on the midblock-crosslinked triblock copolymer to confirm its AEM properties. The synthetic results and characterizations of the midblock-crosslinked triblock copolymer will be discussed in detail.
