| 摘 要： | 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。

| Abstract: | Functionalized fluorinated poly (arylene ether oxadiazole) (FPAEO) based cross-linked anion exchange membranes (AEMs) with bifunctional agents were prepared via copolymerization, bromination and solution casting using a thermal cross-linking method. FPAEO-TM synthesized via 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 by N-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). |
