摘　　要：采用先磺化法,通过控制双酚芴、二氟苯甲酮和磺化二氟苯甲酮的比例,合成了磺化聚芴醚酮,对其结构进行表征,并制备成质子交换膜,对其性能进行了研究.结果表明其具有高的热稳定性、化学稳定性及足够的机械性能,同时还具有较好电池性能.Sulfonated Poly （fluorenyl ether ketone） （SPFEK） was synthesized using direct synthesis method from sulfonated monomer by controlling the mole ratio of bisphenol fluorine, difluorobenzophenone and sulfonated difluorobenzophenone. The structure of the polymer was characterized by HNMR and its properties were investigated. As the result, the SPEFK membranes have not only high thermal and chemical stability, enough mechanical strength, but also superior operational performance in a single PEMFC.
