| 摘 要： | 将磺化二氯二苯砜(SDCDPS)、二氯二苯砜(DCDPS)与4,4′-联苯酚(BP)通过亲核缩聚反应得到一系列具有不同磺化度的磺化聚芳醚砜(SPAES)共聚物.通过FT-IR,TGA和DSC等分析方法对其结构及性能进行表征.并用透射电镜对其内部形态进行分析,建立了结构与性能之间的关系.研究了不同磺化度对膜性能的影响.结果表明,聚合物中磺酸基团的增多导致了磺化聚芳醚砜膜的吸水率、离子交换容量、质子传导率和甲醇渗透系数的增加.通过对膜的综合性能评价发现,磺化度为0.8的磺化聚芳醚砜膜在80℃时的质子传导率为0.116S/cm,100℃时的质子传导率为0.126S/cm,均高于Nafion117膜(0.114S/cm和0.117S/cm),且甲醇渗透系数为8.4×10-7cm2/s,远远低于Nafion117膜(2.1×10-6cm2/s).

| Abstract: | A series of sulfonated poly(arylene ether sulfone)(SPAES) copolymers with different degree of sulfonation(D_s) were synthesized by aromatic nucleophilic polycondensation of 3,3'-disulfonate-4,4'-dichlorodiphenylsulfone(SDCDPS),4,4'-dichlorodiphenylsulfone(DCDPS) and 4,4'-biphenol(BP).Synthesized sulfonated copolymers were characterized by FT-IR,TGA and DSC.Moreover,the microstructure of membranes was investigated by TEM,and the relationship between structure and performance was established.The influence of ... |
