Abstract

본 발명은 중합체 용매를 함유하는 방사원액을 노즐에서 토출시켜 중합 용액을 제조함에 있어서, 2종의 중합체를 각각 용매에 용해시킨 2종의 방사원액을 제조하여 3중관형 노즐을 사용, 하나의 방사원액은 3중 관형노즐에서 내부 응고액과 접촉시키고, 다른 하나의 방사원액은 노즐에서 토출 후 외부응고액에 의해 접촉응고시키면서 습식 또는 건식방사 시킴을 특징으로 하는 이성분 중공사막의 제조방법에 관한 것으로, 본 발명의 중공사막은 종래의 중공사막에 비해 투과성능이 매우 우수하고 기계적 특성 및 내화학성이 크게 개선되어 한외여과막, 역삼투막, 기체분리막의 새로운 제조 방법으로 적용이 가능하다.
