Abstract
The present invention relates to a complex and a material containing the same for oil-water separation. The preparation process of the complex is simple. The complex shows lipophilicity, superhydrophobicity, and super water-repellency since a zinc oxide particle layer, in which zinc oxide particles are agglomerated in a micro-nano structure, and a super-hydrophobic coating layer having low surface energy are sequentially formed on a surface of a polymer matrix having a cavernous porous structure, and thus the complex has high oil-water separation efficiency and high durability. When a magnetic particle layer exhibiting magnetism is provided between the zinc oxide particle layer and the super-hydrophobic coating layer, the positional control and collection of the complex is easy, and thus the complex can be helpfully used as a material for oil absorption type oil-water separation, which is used in large-scale oil-water separation, such as the removal of oil spilled into the ocean.
