Method of preparing ion-exchange membrane using chemical modification and ion-exchange membrane prepared thereby |
| abstract |
The present inventive concept relates to a method of preparing an ion-exchange membrane using a chemical modification and an ion-exchange membrane prepared thereby. More specifically, the present inventive concept relates to a method of preparing an ion-exchange membrane, which is characterized by modifying sulfonic acid groups of a perfluorinated sulfonic acid electrolyte membrane with carboxyl groups and includes chlorinating sulfonic acid groups of a perfluorinated sulfonic acid electrolyte membrane; nitrilating the chlorinated electrolyte membrane; and hydrolyzing the nitrilated electrolyte membrane, and an ion-exchange membrane chemically modified thereby. |
