摘要： 利用含溴苯侧基的聚芳醚砜(PES-Br)和1,1,2,2-四氟-2-(1,1,2,2-四氟-2-碘乙氧基)乙烷磺酸钾(PSA-K)进行Ullman偶联反应, 制备了新型含全氟磺酸侧链的聚芳醚砜(PES-PSA), 全氟磺酸的引入量为50%. 在离子交换容量(IEC)为0.907 meq./g, 80 ℃, 相对湿度为100%时, PES-PSA质子传导率达到0.039 S/cm, 表现出较高的质子传导能力. 其较低的IEC值使膜材料表现出良好的热稳定性和尺寸稳定性.

关键词: 全氟磺酸, 聚芳醚砜, 质子交换膜

Abstract: A novel poly(arylene ether sulfone) with a perfluoroalkyl sulfonic acid pendant(PES-PSA) was synthesized by Ullman coupling of poly{oxy-4,4'-oxy-4,4'-diphenylsulfone}(PES-Br) and potassium 1,1,2,2-tetrafluoro-2-(1,1,2,2-tetrafluoro-2-iodo-ethoxy)ethanesulfonate(PSA-K). The introduction of the perfluoroalkyl sulfonic acids was successfully carried out with high conversion(c.a. 50%) to yield the desired polymer. Even with a low ion exchange capacity(IEC) of 0.907 meq./g, PES-PSA exhibited a high proton conductivity of 0.039 S/cm at 80 ℃ under 100% relative humidity. The low IEC makes the membrane own good dimensional stability and thermal stability. Other membrane properties, such as thermal properties and water uptake were also investigated in detail.

Key words: Perfluoroalkyl sulfonic acid, Poly(aryl ether sulfones), Proton exchange membrane
