Zusammenfassung:The present invention provides a negative ion exchange membrane containing a hydroxyl group (OH-)-added piperidinium (Pip) conducting functional group in which a hydroxyl group (OH-)-added piperidinium (Pip) conducting head group is grafted onto a polymer main chain and having poly(2,6-dimethyl-1,4-phenylene oxide) with 4-hydroxy-piperidinium and tropinium conducting head groups and PPOs developed, and more specifically, provide a negative ion exchange membrane formed from these molecules. According to the present invention, the chemical and physical stability of the membrane is further improved due to physical cross-linking through hydrogen bonding. 본 발명에서는 하이드록실기(OH-)가 부가된 피페리디늄(piperidinium, Pip) 전도성 헤드 그룹이 고분자 주쇄에 그라프팅 결합된 하이드록실기(OH-)가 부가된 피페리디늄(piperidinium, Pip) 전도성 작용기를 포함하는 음이온 교환막을 제공하며, 구체적으로 4-하이드록시-피페리디늄 및 트로피늄 전도성 헤드 그룹(conducting head groups)을 갖는 폴리(2,6-디메틸-1,4-페닐렌 옥사이드)(Poly(2,6-dimethyl-1,4-phenylene oxide)s, (PPO)s)가 개발되었으며, 이러한 분자들로부터 형성된 음이온 교환막을 제공한다.
