Functionalized fluorinated poly (arylene ether oxadiazole) (FPAEO) based cross-linked anion exchange membranes (AEMs) with bifunctional agents were preparedvia copolymerization, bromination and solution casting using a thermal cross-linking method. FPAEO-TM synthesizedvia copolymerization of 4,4'-isopropylidenebis (2,6-dimethylphenol) (TM-BPA) and 2,5-bis(2,3,4,5,6-pentafluorophenyl)-1,3,4-oxadiazole(FPOx) was brominated byN-bromosuccinimide (NBS), thereby avoiding chloromethylation, which required carcinogenic reagents.1-vinylimidazole acted as a bifunctional agent and played two roles:it served as an ion exchange functional group which provided membranes high conductivity,or as a crosslinking agent to improve the membranes'characteristics. The mambrane's conductivity is 9.02×10?2 S·cm?1 at 80℃ and methanol permeability is 1.89×10?7 cm2·s?1(20℃). Membranes had the potential to be used in alkaline fuel cell alkaline (AFC).%以N-溴代丁二酰亚胺(NBS)为溴化试剂,对十氟 二唑与四甲基双酚A(TM-BPA)聚合的聚合物主链进行溴化,随后以N-乙烯基咪唑作为双功能化试剂进行功能化,制备了含有双功能化试剂的氟化聚 二唑芳醚阴离子交换膜.其中,功能化试剂(作为离子交换的功能基传导离子及作为膜内分子的交联点)改善膜物理性质.制备的阴离子交换膜在80℃下的离子传导率为9.02×10?2 S·cm?1,甲醇渗透率为1.89×10?7 cm2·s?1(20℃),在碱性燃料电池中具有应用潜力.
