Research Abstract |
We aimed to fabricate a magnetic field-responsive membrane and its new separation processes and systems. For achieving this membrane, we prepared poly-NIPAM-grafted membrane from polycarbonate porous substrate via plasma graft polymerization. Then, we isolated grafted poly-NIPAM, and measured molecular weight distribution by GPC. Finally we clarified the relationship between grafting amount, the structure of pores, and pressure-driven permeation flux. Also, we showed that an ion gating membrane, which was grafted poly-NIPAM-co-BCAm (Benzo[18]crown-6-acrylamide), can response in water/ethanol mixture. This leads to treat this membrane in organic solvent/water mixture for preparing a magnetic-field responsive membrane.
