Superhydrophobic surfaces typically mimic nature’s famously self-cleaning lotus leaves.[18]. Their repellent properties are based on the creation of a composite air/solid interface by introducing topographic features at the micro- and nanoscale to a surface bearing a chemical functionality that maximizes the contact angle with the liquid to be repelled.[19,20,21,22]
It has been recognized that the design of an oleophobic coating requires the presence of re-entrant curvature, i.e. surface topography features that bend towards the substrate and form angles with the substrates below 90°
