The Lotus Effect

 

Self Cleaning!

Some plant leaves just can’t get wet or dirty! Lotus plants have superhydrophobic surfaces.  Water drops that fall onto them bead up and roll off. These leaves not only stay dry, but the droplets pick up small particles of dirt as they roll, so that the lotus leaves are even self-cleaning.

How Does It Stay Dry?

The lotus leaves have  nanostructures on their surfaces.  These nanostructures are coated with hydrophobic wax crystals approximately 1 nm in diameter.This makes the surface at the nanoscale quite rough. This rough surface is more hydrophobic than a smooth surface would be.
