摘要:
以氯磺酸为磺化剂,浓硫酸为溶剂,合成磺化聚醚砜膜(SPES),通过对磺化聚醚砜膜取向,改变膜亲水区和疏水区微相结构的空间形状和排布方式.应用扫描电子显微镜和X射线衍射仪研究了SPES表面结构和微相结构的变化,采用衰减全反射原位红外光谱研究了SPES膜吸附水分子的动态过程和氢键变化,探讨SPES膜中水分子层结构的变化规律,采用交流阻抗法研究了取向对SPES电学性能的影响.结果表明,经取向后SPES膜聚合物分子链和亲水区空间形状和排布方式发生了一定程度的变化,膜内多层水分子结构更容易形成并相互连接,有利于亲水区离子传递通道的形成和延长,改善质子传导过程,提高电导率.
Abstract:
Sulfonated polyethersulfone(SPES)membranes were orientated with different forces by thermal mechanical analyzer.The effects of tropism on its proton conductivity of SPES were investigated by Solatron phase analyzer,and its membrane morphology and proton conducting process were detected.It was found that the tropism of SPES has great effect on the arrangement of polymer chains and proton conductivity of SPES.The orientated SPES were more liable to achieve multilayer water which facilitated the exchange and transfer of hydrated proton among these hydrophilic sulfonic acid groups.This resulted in the increase of the conductivity of SPES.
