A lot of membrane separation methods were introduced in recent years. In this study, we went to perform a facile fabrication of conducting polymer modified membrane with immobile dopant ions. These modified membranes would be used for controling organic ion transport by adding constant and pulse potentials. First, gold was sputtered on the PC(polycarbonate) membrane and then a polypyrrole layer was electrochemically deposited on the Au surface in aqueous solution until the pores were covered perfectly. Then Methylene Blue(MB) permeation experiment progressed under various potential conditions. Since MB is a cationic dye, it’s flux can be effected by the positive and negative potentials. In this study, we demonstrated that the organic ion permeate through the membrane can controled by adding constant and pulse potentials and proposed the ion transport mechanisms. This work was supported by the Energy & Resource of the Korea Institute of Energy Technology Evaluation and Planning(KETEP) grant funded by the Korea government Ministry of Knowledge Economy(No. 2010501010002B)
