Beschreibung
Zusammenfassung:	The present invention relates to an omniphobic membrane and a method for manufacturing the same and, more specifically, to an omniphobic membrane and a method for manufacturing the same, wherein a membrane support is surface-modified with a hydrophobic molybdenum disulfide composite (MoS_2-g-PVDF) in which molybdenum disulfide (MoS_2) is grafted onto polyvinylidene fluoride (PVDF), thereby effectively removing oily organic substances from a feed solution with excellent fouling resistance, low wettability, high water permeability and high stability. 본 발명은 옴니포빅 멤브레인 및 이의 제조방법에 관한 것으로서, 보다 상세하게는 멤브레인 지지체를 이황화몰리브덴(MoS2)이폴리플루오르화비닐리덴(PVDF)에 그래프팅된(grafted) 소수성 이황화몰리브덴 복합체(MoS2-g-PVDF)로 표면개질하여 우수한 내오염성, 낮은 습윤성, 높은 수투과도 및 높은 안정성으로 피드용액에서 오일성 유기물질을 효과적으로 제거할 수 있는 옴니포빅 멤브레인 및 이의 제조방법에 관한 것이다.
