초 록 본 리뷰에서는 에너지분야 응용을 위해 사용된 이온교환막을 이용한 분리막 공정에 대하여 정리하였다. 이온교환막은 기능, 균일상, 불균일상과 같은 형태, 사용된 고분자의 종류에 따라 구분되었으며, 양이온 및 음이온 교환막을 제조하 기 위한 다양한 방법에 대하여 논문을 참조하여 정리하였다. 이온교환막을 제조하기 위한 최신 연구결과 동향이 보고 되었으며, 본 리뷰에서는 분리막의 제조 및 발전되어온 내용과, 분리막을 미래지향적 기술에 사용하기 위한 잠재적 응용분야에 대하여 논의하였다. Abstract In this review, we summarized some of membrane processes using the ion exchange membrane typically used in energy applications. Ion exchange membranes are classified according to their functions, formations (e.g.

Furthermore, various methods to prepare cation exchange membranes and anion exchange membranes were discussed in detail and also illustrated through a thorough review of the literature works. There are numerous reports highlighting recent research trends in the ion exchange membrane fabrication, however, in this review we will focus more on discussing the development made in ion exchange membranes and their potential usages in future technologies. are attached to polymer backbones, and the density of the ionic site in the backbone determines various properties including the ion conductivity, mechanical stability, and chemical stability. For example, a membrane with a high degree of ionic groups causes high ionic conductivity combined with low mechanical strength. However, a high degree of ionic transport sites improves the electrochemical properties of the membrane but decreases the mechanical properties and chemical durability. Thus, these properties must be compromised in order to develop ion exchange membranes with high properties. In this review, we summarize the different types of ion exchange membranes, preparation procedures, characterizations, and applications for membrane processes.
