Beschreibung
Zusammenfassung:	Through the present invention, an ion exchange membrane comprising an arylene-based hydrocarbon polymer as a main chain can be provided, wherein the main chain comprises at least one side chain, and at least one of side chains comprises a sulfonated aliphatic compound. A method for manufacturing the ion exchange membrane also can be provided. Further, the present invention can provide an ion exchange membrane which is inexpensive and does not easily deteriorate by vanadium ions and exhibits excellent properties with high proton conductivity, and a vanadium battery using the ion exchange membrane. 본 발명을 통해서, 아릴렌계 탄화수소 고분자 화합물을 주쇄로 포함하고, 상기 주쇄는 적어도 하나 이상의 측쇄를 포함하며, 상기 각각의 측쇄들 중에서 적어도 하나 이상은 술폰화된 지방족 화합물을 포함하는 이온 교환 멤브레인 및 이의 제조방법을 제공할 수 있고, 저렴하면서도 바나듐 이온에 의해 쉽게 열화되지 않고, 프로톤 전도도가 높은 우수한 특성을 나타내는 이온 교환 멤브레인 및 이를 이용한 바나듐 전지를 제공할 수 있다.
