Title
(KO) 복합 반투막
Abstract
(KO)
본 발명은 기재와, 다공성 지지층과, 분리 기능층을 구비하고, 상기 분리 기능층은, 가교 방향족 폴리아미드를 갖는 제1층과, 불소 원자를 갖는 지방족 폴리아미드를 갖는 피복층을 함유하고, 상기 복합 반투막의 상기 피복층측으로부터의 X선 광전자 분광 측정에 있어서 측정된, 전체 원소의 합계 원자수에 대한 불소 원자의 원자수의 비율이 0.5% 이상 8% 이하이고, 상기 X선 광전자 분광 측정에 있어서 측정된, 산소 원자의 원자수에 대한 질소 원자의 원자수의 비가 0.8 이상 1.3 이하인, 복합 반투막에 관한 것이다.
