摘要： 以聚偏氟乙烯(PVDF)-六氟丙烯(HFP)中PVDF的仲氟原子直接引发甲基丙烯酸(3-磺酸钾)丙酯(SPMA)的原子转移自由基聚合，成功得到以PVDF-HFP为主链、侧链含磺酸基团的接枝聚合物(PVDF-HFP-g-PSPMA)质子交换膜. 通过红外、核磁分析方法对PVDF-HFP-g-PSPMA的结构进行表征. 反应不同时间得到的PVDF-HFP-g-PSPMA离子交换容量为0.051~0.59 meq/g，质子传导率为(2.58~30.9)×10-2 S/m.

Abstract: Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) grafted poly(sulfopropyl methacrylate) (PSPMA) (PVDF-HFP-g-PSPMA) copolymer as proton conductive electrolyte by atom transfer radical polymerization of sulfopropyl methacrylate (SPMA) at the secondary halogenated sites of PVDF-HFP was prepared and characterized. The structure of PVDF-HFP-g-PSPMA copolymer was verified by FT-IR spectroscopy and proton nuclear magnetic resonance spectrometry. The PVDF-HFP-g-PSPMA membrane showed the ion exchange chromatography value ranging from 0.05 to 0.59 meq/g and the proton conductivity from 2.58×10-4 to 3.09×10-3 S/cm, and its property could be modulated by controlling the polymerization time.

Key words: Polymer electrolyte membrane, ATRP, PVDF-HFP
