Title:
CARBAZOLE-BASED ANION EXCHANGE MATERIAL, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/172706
Kind Code:
A1
Abstract:
The present invention relates to a carbazole-based anion exchange material, a preparation method therefor and a use thereof, and, more specifically, to: an anion exchange material, a separation membrane comprising same, a preparation method therefor, and a use thereof, the material being usable as a membrane for water electrolysis, a redox flow battery, a fuel cell, carbon dioxide reduction, electrochemical production and decomposition of ammonia, electrodialysis (ED), reverse electrodialysis (RED) or capacitive deionization (CDI); According to the present invention, provided is an anion exchange material in which all the bonds between monomers, that form a main chain on the basis of a carbazole-based material with excellent stability, are formed from C-C bonds, so that molecular weight is remarkably improved while the anion exchange material is soluble in a solvent, and thus a separation membrane with improved physicochemical stability and durability can be manufactured.
