Abstract: Provided is a polymeric material having a micro-nano composite structure, a device including the same, and a method of manufacturing the polymeric material. The polymeric material includes a polymer fiber or film, wherein the polymer fiber or film has, on a surface thereof, a micro-nano composite structure including a microstructure containing concavo-convex grooves having a microscale semi-cylindrical shape (“”) and a nanopattern containing nanoscale protrusions formed on a surface of the microstructure. The polymeric material has excellent absorbency and hydrophilic or super-hydrophilic surface properties, and also has oleophobic or super-oleophilic properties in water, and thus may be effectively applied to fields such as oil-water separation, purification, and filters. The polymeric material may be readily manufactured through an environmentally friendly, large-area atmospheric pressure plasma process.
