Abstract

See full text

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.
