| 摘 要： | 将聚(2-丙烯酰胺-2-甲基丙磺酸锂)(PAMPSLi)与羧甲基纤维素钠(CMC)共混制备了PAMPSLi-羧甲基纤维素钠/壳聚糖(CS)双极膜(BPM).实验结果表明,在CMC阳膜层中添加PAMPSLi可提高其离子交换容量和氢离子渗透性能.与CMC/CS双极膜相比,PAMPSLi-CMC/CS双极膜的电阻压降(IR降)和溶胀度均降低.当PAMPSLi的添加量为4%,电流密度为105mA.cm-2时,PAMPSLi-CMC/CS双极膜的IR降为2.0V.

| Abstract: | The carboxymethyl cellulose(CMC) cation exchange membrane was modified by poly(2-acrylamide-2-methylpropanesulfonic acid lithium)(PAMPSLi) to prepare the PAMPSLi-carboxymethyl cellulose/chitosan(CS) bipolar membrane(BPM).The results showed that the ion exchange capacity and hydrogen ion transmigration rate of the PAMPSLi-CMC cation exchange membrane were increased.In comparison with the CMC/CS BPM,both the IR drop and the swelling degree of the PAMPSLi-CMC/CS BPM were decreased.When the addition amount of PAMPSLi was 4%,the IR drop of the PAMPSLi-CMC/CS BPM was 2.0 V at the high current density of 105 mA·cm-2. |
