摘要：

In order to develop anion exchange membranes (AEMs) with high ionic conductivity, low swelling ratio (SR) and long-term alkaline stability, a series of crosslinked polybenzimidazole-based AEMs (FPBI-QPVC(x)) were prepared. We herein demonstrated that the integration of a partially fluorinated polybenzimidazole and quaternized poly (vinylbenzyl chloride) benefits the fabrication of the AEMs with well-defined hydrophilic/hydrophobic phase-segregated structure, leading to a relative high hydroxide conductivity of 91.7 mS cm(-1) at 80 degrees C for FPBI-QPVC(2)(.5). The existence of a crosslinking...
