Zusammenfassung:The present invention relates to a novel limited interfacial polymerization method, and to a separation film produced by using the same. According to the present invention, a middle layer having high water permeability is provided on a porous support, and a limited interfacial polymerization is applied on top of the same. Designing an interfacial polymerization selection layer which has low thickness, high density, and less surface projections regardless of types of the supports, it is possible to create high water permeability as well as high selectivity. 본 발명은 신규한 한계 계면 중합법과 이를 이용하여 제조한 분리막에 관한 것이다.  본 발명은 다공성 지지체 위에 높은 수투과도를 가지는 중간층을 도입하고 그 위에 다시 한계 계면 중합을 적용한 것으로, 지지체의 종류에 무관하게 두께가 적으면서 고밀도인 동시에 표면 요철이 적은 계면 중합 선택층을 설계하여 높은 선택도뿐만 아니라 높은 수투과도를 구현할 수 있다.
