Abstract

Abstract: In this paper, hydroxyl-functionalized SPEEK was obtained using NaBH₄ as reducing agent. Ionic liquid 1-carboxy methyl-3-methylimidazolium chloride grafted to hydroxyl-functionalized SPEEK by esterification reaction, the graft polymer obtained. The experimental results showed that the ionic liquid modified SPEEK membrane had lower water absorption and swelling, while the electrical conductivity had been significantly improved.

Key words: sulfonated poly (ether ether ketone), ionic liquid, ionic exchange membrane, modification

摘要： 通过NaBH₄还原磺化聚醚醚酮(SPEEK)得到羟基功能化的SPEEK后，采用酯化反应将离子液体1-羧甲基-3-甲基咪唑氯盐接枝到磺化聚醚醚酮上得到接枝聚合物。实验结果表明：离子液体修饰后的磺化聚醚醚酮离子交换膜吸水率和溶胀度降低，而导电率得到了显著提高。
