| Zusammenfassung: | The present invention relates to a hydrophilic polyolefin hollow fiber membrane for a water purifier which includes: a polyolefin hollow fiber membrane; and a coating layer of an olefin-based ionomer on the surface of the hollow fiber membrane. The hydrophilic polyolefin hollow fiber membrane manufactured according to the present invention has high mechanical intensity and significantly improved water permeability in comparison with a conventional hollow fiber membrane for a water purifier, thereby being useful as a hollow fiber membrane filter of the water purifier.
본 발명은 폴리올레핀 중공사막; 및 상기 중공사막의 표면에 올레핀계 이오노머의 코팅층;을 포함하는 정수기용 친수성 폴리올레핀 중공사막에 관한 것이다. 본 발명에 따라 제조된 친수성 폴리올레핀 중공사막은 종래 정수기용 중공사막에 비하여 수투과도가 크게 향상되고 기계적 강도도 우수하여 정수기의 중공사막 필터로서 유용하다. |
