Abstract
The present inventive concept relates to a chemically modified anion exchange membrane and a method of preparing the same and, more particularly, an anion exchange membrane in which sulfonic acid groups in a perfluorinated sulfonic acid electrolyte membrane are substituted with anion conductive groups such as an ammonium group, a phosphonium group, an imidazolium group, a pyridinium group and a sulfonium group, and a method of preparing an anion exchange membrane by chemically modifying sulfonic acid groups in a perfluorinated sulfonic acid electrolyte membrane.
Claims5
An anion exchange membrane in which sulfonic acid groups in a perfluorinated sulfonic acid electrolyte membrane are substituted with anion-conductive functional groups, wherein the anion-conductive functional groups are selected from the group consisting of a phosphonium group, a pyridinium group, an imidazolium group and a sulfonium group.
