中文摘要	制备了3种聚偏氟乙烯(PVDF)基离子交换膜,比较了面电阻、离子交换容量(IEC)、含水率和钒离子渗透速率。PVDF与丙烯磺酸钠(SAS)共混制备的PVDF-SAS膜的面电阻最小,为1.2Ω.cm2,IEC达到1.16 mmol/g。FT-IR分析表明:这种膜在制备过程中,SAS的C C键在长时间高温后发生了聚合反应,与PVDF形成了互穿网络结构。自放电实验表明:所制备的膜在开路状态下,钒离子渗透速率小于8.8×10-3V/h。; Three kinds of polyvinylidene fluoride(PVDF) based ion exchange membranes were prepared,their area resistance,ion exchange capacity(IEC),water content and vanadium ion permeability ratio were compared.The PVDF-sodium allylsulfonate(SAS) membrane prepared with a homogeneous solution of PVDF and SAS had the lowest area resistance of 1.2 Ω·cm2,its IEC was 1.16 mmol/g.FT-IR analysis showed that the CC bond of SAS polymerized after long time under high temperature and formed inter network structure with PVDF during the processes of the membranes formation.Self-discharge test showed that the vanadium ions permeation rate of the prepared membrane was below 8.8×10-3 V/h at open circuit condition.; 国家“863”项目(2007AA05Z245); 国家自然科学基金项目(20676068,20876086)
