It is made from superhydrophobic (also known as ultrahydrophobic) materials, and typically cause an almost imperceptibly thin layer of air to form on top of a surface.
[1][2] Generally speaking, superhydrophobic coatings are made from composite materials where one component provides the roughness and the other provides low surface energy.
[3] Superhydrophobic coatings are also found in nature; they appear on plant leaves, such as the lotus leaf, and some insect wings.
The recessed surface has a proportionately diminished attraction foreign liquids or solids and permanently stays cleaner.
In addition, superhydrophobic coatings have potential uses in vehicle windshields to prevent rain droplets from clinging to the glass, to improve driving visibility.
[14][15] Due to their fragility, superhydrophobic coatings can find usage in sealed environments which are not exposed to wear or cleaning, such as electronic components (like the inside of smartphones) and air conditioning heat transfer fins, to protect from moisture and prevent corrosion.
However, the current state of the art for this technology is hindered in terms of the weak durability of the coating making it unsuitable for most applications.
