Abstract

The possibility of modification of ion-exchange membranes with high pore and channel volumes and the effect of doping on the membrane properties have been studied. Hybrid membranes based on sulfonated polystyrene grafted onto polymethylpentene and cesium acid phosphotungstate have been synthesized by the in situ method. It has been shown that modification of these membranes leads to an increase in conductivity to 34.8 mS/cm at 25°С in contact with water. The chloride anion transport numbers for the original and modified membranes are about 4%.

磷钨酸铯盐改性对磺化聚苯乙烯接枝膜性能的影响

摘要

研究了具有高孔隙和通道体积的离子交换膜的改性可能性以及掺杂对膜性能的影响。通过原位合成了基于磺化聚苯乙烯接枝到聚甲基戊烯和铯酸磷钨酸盐上的杂化膜。已经表明，这些膜的改性导致在与水接触的25°C下电导率增加至34.8 mS / cm。原始膜和改性膜的氯离子迁移率约为4％。
