ANION EXCHANGE MEMBRANE FOR REDOX FLOW BATTERY AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: An anion exchange membrane is provided to contain an excellent benzene structure with excellent dimensional stability and to have excellent durability in a redox flow battery. CONSTITUTION: A manufacturing method of an anion exchange membrane comprises 4-vinylbenzyl, styrene, and 2-hydroxyethyl acrylate as a monomer to synthesize a 4-vinylbenzyl chloride-styrene-2-hydroxyethyl acrylate copolymer; a step of aminatng the 4-vinylbenzyl chloride-styrene-2-hydroxyethyl acrylate copolymer; and a step of adding a crosslinking agent to the copolymer and manufacturing the anion exchange membrane by a crosslinking reaction.
