superhydrofobic
Superhydrophobic is a term used to describe a surface that repels water to an extreme degree. When water comes into contact with a superhydrophobic surface, it forms almost perfect spheres and rolls off with minimal contact. This phenomenon is characterized by a contact angle of greater than 150 degrees. This high contact angle is achieved through a combination of surface roughness and low surface energy.
The roughness at the micro or nanoscale creates air pockets between the water droplet and the surface.
Superhydrophobic properties are inspired by natural phenomena, like the water-repellent surfaces found on lotus leaves, often
