Smart bioinspired anti-wetted surfaces: Perspectives, fabrication, stability and applications

Abstract The presence of water on the surface of material is not always desired. The prolonged stay of droplet on surface can deteriorate its physical and chemical properties. Bioinspired anti-wetted surfaces can be thought of an alternative that can protect the surface by expelling the possibility of water residence on the surface for long period. These surfaces show remarkable potential due to their diverse applications such as self-cleaning, transparency, oil-water separation, anti-corrosion, anti-microbial and have gained attention due to their low cost, ease of processing, and compatibility with a variety of materials and applications. This paper consists the fundamental concept of wetting phenomena. Further it comprises the details of different techniques used for fabricating these surfaces. Review also discusses about the stability of these surfaces and ends with future prospects which gives helps in development of new and advanced super-hydrophobic/oleophobic surfaces.
