The present invention relates to a hollow fiber membrane for separating oxygen, and especially, to a hollow fiber membrane having a coating layer formed on an inner surface comprising derivatives of transition metal-salen for separating oxygen. The hollow fiber membrane for separating oxygen coats an inner surface of a porous and tubular polymer membrane with a coating solution, comprising the derivatives of transition metal-salen, to have excellent selectivity and transmittancy of oxygen gas even under low pressure, and especially, to show high efficiency in oxygen gas separation among combustion flue gas. 본 발명은 산소 분리용 중공사막에 관한 것으로, 특히 전이금속-살렌(salen)유도체를 포함하는 코팅층이 내면에 형성된 산소 분리용 중공사막에 관한 것이다. 본 발명의 산소 분리용 중공사막은 전이금속-살렌 유도체를 포함하는 코팅용액을 다공성 관형 고분자막 내면에 코팅하여 낮은 압력에서도 산소기체의 선택도 및 투과도가 우수하게 되어 특히 연소 배가스 중의 산소기체 분리에 높은 효율을 나타낼 수 있다.
