摘要

分别用八羧基铜酞菁、四磺酸基铜酞菁对海藻酸钠阳膜和四氨基铜酞菁对壳聚糖阴膜进行了改性，制备了金属酞菁衍生物改性海藻酸钠/壳聚糖双极膜，并用热分析、电子万能试验机、接触角测定仪和J-V关系等对改性海藻酸钠/壳聚糖双极膜进行了表征。实验结果表明，金属酞菁衍生物改性海藻酸钠/壳聚糖双极膜的热稳定性、力学性能和亲水性均获得提高。金属酞菁衍生物在双极膜中间界面层形成高荷电区，促进了中间界面层水的解离，从而降低了海藻酸钠/壳聚糖双极膜的膜电压。具有不同取代基的金属酞菁衍生物对中间界面层水解离的催化能力不同，这与不同取代基的金属酞菁衍生物改性膜的亲水性大小有关。

Abstract

The sodium alginate (SA) cation layer was modified by copper octocarboxyphthalocyanine or copper phthalocyanine tetrasulfonic acid

and the chitosan (CS) anion layer was modified by copper tetraaminophthalocyanine to prepare the modified SA/CS bipolar membranes (BPMs).The BPMs were characterized using TG

electric universal testing machine

contact angle measurer and J-V investigation.Experimental results showed that the thermal stability

mechanical properties and hydrophilicity of the BPMs were increased.After modification

high charge density area formed in the interlayer.As the catalytic centers of water splitting in the interlayer

metallophthalocyanine derivatives sped up water splitting into hydrogen ions and hydroxide ions

and lowered the IR drop of the BPMs.The metallophthalocyanine derivatives with dissimilar substituents showed different catalytic ability to water splitting in BPMs

which was in connection with the hydrophilicity of the relevant modified membranes.
