中文摘要：

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0．051～0．59meq／g，质子传导率为（2．58～30．9）×10^-2S／m．

英文摘要：

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.
