Recently, ion exchange membrane has been widely used for the catalyst, recovery of valuable metal, water purification, medical part, and separation of protein. The cationic exchange membrane are required high mechanical perperty, ion exchange capacity and low electrical resistance. In this study, cationic exchange membrane is prepared by triblock copolymer based on styrene and two kinds of acrylate comonomers. We are investigated to the degree of sulfonation(DS), water uptake, ion exchange capacity(IEC) and membrane thickness. |
