Abstract: Owing to the extreme water repellency of lotus leaves, researchers newlinestudied it for more than a century for the underlying principle. Barthlott and newlineNeinhuis in 1997 reported that self-cleaning mechanism of the leaf relies on newlinethe micro-nano hierarchies and low energy cuticular wax readily available on newlinethe surface. Despite of lotus leaves, non-wettable phenomenon is also newlineavailable in most of natural surfaces like mosquito eyes, damselfly wings, newlinewater strider s leg, etc. Bio-mimicking is a novel area of research that newlinedevelops artificial surfaces with nature s properties, which solves majority of newlinethe practical problems like icing of surfaces, staining of fabrics, etc. newlineDeveloping water repellent surfaces with costlier chemicals and sophisticated newlineequipment retards the commercialization activity. In this aspect, it is tried to newlinesome extend to reduce the cost of the coatings comprised of non-wettable newlinephenomenon. The works related to development of excellent load bearing newlineability of self-cleaning surface uses low cost compounds via simple method. newlineThe drag reduction property of a soot coated surface is reported with some newlineadditional features. Urine repellent surface is developed with cost-efficient newlinestearates and porous oxides, thereby it is ready to commercialize. newlineImprovement of the transparency of superhydrophobic coatings with strong newlinebonding to the glass substrates is carried out in spray pyrolysis route, suitable newlinemethod for large scale fabrication process. Some novel applications like newlineconversion of a wound healing bandage into superhydrophobic is also newlineproposed in this work newline newline
