OIL-WATER SEPARATION STRUCTURE, METHOD OF PREPARING THE SAME, OIL-WATER SEPARATOR, AND OIL-WATER SEPARATION METHOD USING OIL-WATER SEPARATOR

摘要

Provided is an oil-water separation structure, a method of manufacturing the same, an oil-water separator including the oil-water separation structure, and an oil-water separation method using the oil-water separator. The oil-water separation structure includes a porous substrate including a plurality of protrusions forming a nano-pattern on at least one surface; and an inorganic particle disposed at an end of at least some portions of the protrusions. The oil-water separation structure has hydrophilic or superhydrophilic surface properties to selectively filter out water and easily separate and retrieve oil from a mixture of water and oil. A manufacturing process of the oil-water separation structure is environmentally friendly and the oil-water separation structure may be manufactured into a large surface area. The oil-water separator including the oil-water separation structure may be repeatedly used and prevent additional environmental pollution.
