Superhydrophobe

Superhydrophobic surfaces such as the leaves of the lotus plant have surfaces that are highly hydrophobic, i.e., extremely difficult to wet. The contact angles of a water droplet exceeds 150° and the roll-off angle is less than 10°.^[1] This is referred to as the Lotus effect.

clipped from lotus-shower.isunet.edu

The Physical Basis

To understand the physics behind the Lotus-Effect, one has to take a look the forces that act upon a drop of liquid on a surface.

clipped from medtechinsider.com

Some insect wings, for example, are superhydrophobic, which is the combined result of their chemistry and the detailed nanoscale structures on their surface.
