摘要:

分别用八羧基铜酞菁[CuPc(COOH)8]和四氨基铜酞菁(CuTAPc)改性海藻酸钠(SA)阳膜层和壳聚糖(CS)阴膜层, 制备了CuPc(COOH)8-SA/CuTAPc-CS双极膜. 实验结果表明, 经八羧基铜酞菁和四氨基铜酞菁改性后, 促进了双极膜中间层水的解离, 增大了阳离子交换膜层和阴离子交换膜层的离子交换容量及H+和OH-的透过率. 与Fe3+改性的Fe-SA/mCS双极膜相比, CuPc(COOH)8-SA/CuTAPc-CS双极膜的阻抗、电阻压降(即IR降)和溶胀度降低. 当电流密度高达120 mA/cm2时, CuPc(COOH)8-SA/CuTAPc-CS双极膜的IR降仅为0.9 V.

Abstract:

The sodium alginate(SA) cation layer and the chitosan(CS) anion layer were modified by copper octocarboxyphthalocyanine[CuPc(COOH)8] and copper tetraaminophthalocyanine(CuTAPc) to prepare the CuPc(COOH)8-SA/CuTAPc-CS bipolar membranes(BPM). The ion exchange capacity and hydrogen ion transmigration rate of the CuPc(COOH)8-SA cation exchange membrane, and the ion exchange capacity and hydroxide ion transmigration rate of the CuTAPc-CS anion exchange membrane were increased. The water splitting rate at the interlayer of the CuPc(COOH)8-SA/CuTAPc-CS BPM was promoted. In comparison with the Fe-SA/mCS BPM modified by Fe3+, the membrane impedance, IR drop and swelling degree of the CuPc(COOH)8-SA/CuTAPc-CS BPM all obviously decreased. The IR drop of the CuPc(COOH)8-SA/CuTAPc-CS BPM was 0.9 V at a higher current density of 120 mA/cm2.
