Ananotextured surface (NTS) is a surface which is covered withnano-sized structures. Such surfaces have one dimension on thenanoscale, i.e., only the thickness of the surface of an object is between 0.1 and 100 nm. They are currently gaining popularity because of their special applications due to their unique physical properties. Nanotextured surfaces are in various forms like cones, columns, or fibers. These are water, ice, oil, and microorganism repellent that is superamphiphobic,anti-icing, andantifouling respectively and thus self-cleaning. They are simultaneouslyanti-reflective and transparent, hence they are termedsmart surfaces.[1]
In research published online October 21, 2013, inAdvanced Materials, of a group of scientists at theU.S. Department of Energy'sBrookhaven National Laboratory (BNL), led by BNL physicist and lead author Antonio Checco, proposed that nanotexturing surfaces in the form of cones produces highlywater-repellent surfaces. These nano-cone textures aresuperhydrophobic or super-water-hating.[2][3]
