摘　　要：从电化学缓解膜污染出发,在聚砜膜表面负载碳纳米管和聚吡咯后形成具有优异导电性能的高分子膜。实验过程中进行了条件优化,其最佳制备条件为:0.25 mol/L的氧化剂FeCl_(3),5℃冰水浴,6 h聚合反应时间,0.4 wt%吡咯浓度和0.08 mg/cm^(2)的碳纳米管用量。通过扫描电镜和傅立叶变换红外光谱显示,碳纳米管能够有效地负载并通过吡咯的聚合锚定在膜表面,形成具备优异导电性能的聚吡咯缠绕碳纳米管的导电层,电化学性能和截留性能测试表明,该导电层可以有效地用作电化学过滤的工作电极。Membrane fouling is an obstacle that has been troubling the development of membrane separation technology.In this study,a novel electronic-conductive composite membrane was prepared by loading carbon nanotubes(CNTs)and chemical polymerizing polypyrrole(PPy)on polysulfone membranes.The optimal preparation conditions were 0.25 mol/L FeCl_(3),5°C ice-water bath,6 h reaction time,0.4 wt%pyrrole and 0.08 mg/cm 2 CNTs,which were optimized during the experiment.And the SEM and FTIR characterization showed that the CNTs could be loaded on the membrane surface efficiently and anchored to the membrane surface by the polymerization of pyrrole.The formation of PPy entangled carbon nanotubes forms a conductive layer with excellent electrical conductivity.Meanwhile,the electrochemical and retention performance tests show that it can be effectively used as a working electrode for electrochemical filtration.
