A review on superhydrophobic materials and coating techniques

Abstract Since the recent year, we have seen the interest in scientist to mimic the natural behaviour, and they tried to mimic the nature’s property of superhydrophobicity artificially and very far they also get succeeded. This superhydrophobic property is very useful in many aspects of life as well as in industries as they have an extensive property to overcame wear, corrosion, biofouling etc. There are different ways to fabricate these coatings, some are chemical and some are physical. In this review paper, we have discussed the theoretical background of superhydrophobicity and discussed the need for a surface to become superhydrophobic like surface energy and roughness and also different ways of fabrication in which some are simple and cost-effective and some are very useful for industries. Also, there are different examples of materials that can show superhydrophobic properties.
