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0.116 S/cm

100℃时的质子传导率为0.126 S/cm

均高于Nafion 117 膜 (0.114 S/cm 和 0.117 S/cm)，且甲醇渗透系数为 8.4×10-7 cm2/s，远远低于Nafion 117 膜 (2.1×10-6 cm2/s).

Abstract

A series of sulfonated poly(arylene ether sulfone) (SPAES) copolymers with different degree of sulfonation (Ds) were synthesized by aromatic nucleophilic polycondensation of 3

3′-disulfonate 4

4′-dichlorodiphenylsulfone (SDCDPS)

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 different Dson the properties of SPAES membranes was studied

and it showed that the increase of sulfonated groups in the polymers led to the increase of water uptake

ion exchange capacity (IEC)

methanol diffusion coefficient and proton conductivitie of the membranes.Physical and electrochemical performances of all membranes were studied thoroughly.The results showed that the proton conductivity of SPAES-2 membrane was 0.116 S/cm at 80℃ and 0.126 S/cm at 100℃

which were higher than those of Nafion 117 membrane (0.114 S/cm and 0.117 S/cm).However

the methanol diffusion coefficient of SPAES-2 membrane only reached 8.4×10-7 cm2/s and was much lower than that of Nafion 117 membrane (2.1×10-6 cm2/s).The new synthesized membranes displayed good potential in application as proton exchange membranes (PEM) in proton exchange membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC).
