Abstract
본 발명의 정삼투막은 친수성 고분자층 및 폴리아미드층이 적층된 구조로서, 친수성 고분자층에 의해 원수부에서 물이 원활히 유입되고, 막의 높은 수투과성이 확보되며, 상기 친수성 고분자층 상에 폴리아미드층이 더 적층됨에 따라, 폴리아미드층으로부터 내오염성, 내화학성이 확보되고, 단일막 구조는 기공사이즈가 커서 1가 이온의 작은 염을 제거하기 어려운 반면, 본 발명의 복합막 구조는 1가 이온까지 제거할 수 있어 고염배제율을 구현할 수 있으며, 역삼투 방향으로 유도용액의 용질이 역 확산되는 것을 방지할 수 있다. 이에, 본 발명의 정삼투막은 정삼투 모드에 요구되는 막의 물성을 충족하고 특히 고농도의 해수담수용으로 유용하게 활용될 수 있다.
Description
도 2는 본 발명의 비교예 1에 따른 폴리술폰 다공성 지지체의 단면을 관찰한 사진이다.
