Abstract: Disclosed are a superhydrophilic surface body, a fabricating method thereof, and a filter for oil and water separation, including a superhydrophilic surface. The method for fabricating a superhydrophilic surface body includes a first step of forming a polyaniline nanofiber layer on a surface of a base material, a second step of changing the polyaniline nanofiber layer into a completely oxidized pernigraniline base state, a third step of forming a self-assembled monomolecular film having a polymer polymerization initiation functional group on a surface of the polyaniline nanofiber layer, and a fourth step of forming a silica layer on a surface of the self-assembled monomolecular film. In the third step, the polyaniline nanofiber layer is reduced to a leucoemeraldine state.

Abstract: A filter structure capable of efficiently separating water and oil using wettability is provided. The filter structure according to an exemplary embodiment of the present invention includes a first filter layer including a plurality of openings, a second filter layer including a plurality of openings and positioned so as to be overlapped with the first filter layer at a distance from each other, and a hydrophobic polymer layer formed on surfaces of the first filter layer and the second filter layer. The first filter layer and the second filter layer include surfaces each having a dual-scale protrusion and depression structure as a combination of a micro-scale structure and a nano-scale structure, and the hydrophobic polymer layer is formed along curves of the protrusion and depression structure.
