Abstract: A super-hydrophobic fiber of the present disclosure includes: a nano-needle fiber having a surface including needle-shaped nano structures; and a coating layer disposed on the surface including the nano structures, and containing a hydrophobic material. The fiber has no aging effect, and thus, is excellent in durability, and has such a large contact angle and such as small sliding angle that the fiber may not be wet with water. A method for fabricating the super-hydrophobic fiber includes: a preparation step of preparing a pre-treating fiber; an etching step of etching a surface and an inner portion of the pre-treating fiber to fabricate a nano-needle fiber having a surface on which needle-shaped nano structures are formed; and a coating step of forming a coating layer containing a hydrophobic material, and enables mass production and is performed by simple processes.Further, an article including the super-hydrophobic fiber is an article in which no liquid drop is absorbed, scarcely adsorbs a contaminant, needs not be dried, and thus, may be widely applied even to recreational articles.

Abstract: Provided are a method of producing a nano composite structure and a nano composite structure produced by using the same. The method comprises producing a substrate; placing a metal net structure above the substrate; and plasma treating the substrate above which the metal net structure is placed. The method allows a nano composite structure with a nano patterned structure on its overall surface to be easily produced. The nano composite structure includes a substrate having a plurality of first protrusions constituting a nano pattern on its surface; and an inorganic particle disposed on an end of at least a portion of the first protrusions.
