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.

Abstract: The present disclosure relates to a filter apparatus for oil-water separation, and according to an embodiment of the present disclosure, when the filter apparatus for oil-water separation is mounted in a mixed fluid storage tank for storing a mixed fluid collected in seas or rivers in the event that an oil spill accident occurs, it is possible to drain off only water in the mixed fluid.
In addition, it is possible to increase the storage efficiency of the mixed fluid storage tank by selectively draining and removing only water other than oil and impurities in the mixed fluid stored in the mixed fluid storage tank.
