Superhydrophobicity is a property of a coating or material that requires the following conditions:

1) A water contact angle greater than 150 degrees

2) For a water droplet at rest on the coating or material surface, the angle of tilt required for the droplet to go into motion must be low (< a few degrees)

3) The surface of the coating or material must exhibit a low level of contact angle hysteresis* (< a few degrees)

*Contact angle hysteresis refers to the difference between the advancing and receding water contact angles on the surface. The difference in contact angles while filling and withdrawing fluid from the droplet is measured.
