Generally speaking, the superhydrophobic surface is defined when the static contact angle (CA) of the superhydrophobic material surface with water is greater than 150° and the rolling angle (SA) is less than 10°. Lotus leaf is the first superhydrophobic material discovered by human beings in nature, so superhydrophobic effect is also called "lotus leaf effect". Since the "lotus leaf effect" is discovered, the superhydrophobic property has been widely concerned by scholars. Because superhydrophobic materials have excellent anti-fouling, anti-corrosion, anti-adhesion, self-cleaning and resistance reduction properties, they are widely used in chemical, food, medical, shipping and other aspects.
