A polymer material having a micro-nano composite structure, an apparatus including the same, and a method of manufacturing the polymer material are provided. The polymer material includes a polymer fiber or a membrane, and the polymer fiber or membrane is on a surface, a microscale semi-cylindrical (" And a micro-nano composite structure consisting of a microstructure including "type) uneven grooves; and a nano pattern including nanoscale protrusions formed on the surface of the microstructure. The polymer material has excellent hygroscopicity and hydrophilicity. To super-hydrophilic surface properties, and possesses oleophobic or super-oleophobic properties in water, and can be effectively applied to fields such as oil-water separation, purification, filters, etc. The polymer material is environmentally friendly and easily manufactured through an atmospheric pressure plasma process capable of large area can do. |
