The present invention relates to oil-water separating materials and a method for producing the same. The oil-water separating materials include a composite in which a zinc oxide particle layer where two or more zinc oxide particles aggregate randomly in a radial manner to form a micro-nanostructure on the basis of one arbitrary point on the surface of a melamine resin matrix having a porous, foamed structure; and a superhydrophobic coating layer are sequentially formed. Thus, the oil-water separating materials are not only excellent in durability, but also have an advantage that the average BET specific surface area is large and oil-water separation efficiency is excellent by being lipophilic, superhydrophobic, and super-water repellent. Therefore, the materials can be effectively used as oil-absorption-type, oil-water separating materials used for large-scale oil-water separation such as oil removal from the ocean. 본 발명은 유수분리용 재료 및 이의 제조방법에 관한 것으로, 상기 유수분리용 재료는 해면상의 다공성 구조를 갖는 멜라민 수지 매트릭스 표면의 임의의 한 지점을 기준으로 2 이상의 산화아연 입자들이 랜덤 방사형으로 응집되어 마이크로 나노 구조를 이루는 산화아연 입자층과 초소수성 코팅층이 순차적으로 형성된 복합체를 포함하여 내구성이 뛰어날 뿐만 아니라 평균 BET 비표면적이 넓고, 친유성, 초소수성 및 초발수성을 나타내어 유수 분리 효율이 우수하므로 해양에 유출된 오일 제거와 같이 대면적 유수 분리에 사용되는 오일 흡착식 유수 분리용 재료로 유용하게 사용할 수 있다.
