Recent advances in superhydrophobic surfaces for practical applications: A review

Over the past decade, there have been many successful attempts at artificially reproducing the surface structures found on natural superhydrophobic surfaces. The researchers have been working to mimic the nature by inducing superhydrophobic properties into a variety of material surfaces so that they exhibit non-wetting and self-cleaning properties. The superhydrophobic surfaces exhibits the water contact angles greater than 150° and roll-off angle less than 10°. Many diverse applications have been found in the fields, such as space, textiles, marine, defense, automotive, biomedical applications and engineering, sensors, apparels, and so on. This review paper is about the theories, fundamentals and recent developments in the field of superhydrophobic surfaces and their potential applications.
