New Water-Repellant Material Mimics Lotus Leaves

The lotus leaf, better known as the water lily, is considered sacred in Asian religions for its ability to stay dry and clean. When water drops on the leaf, it beads up and rolls off the waxy surface, washing away dirt as it goes.

In religious circles, this characteristic makes the lotus leaf a symbol of purity. Scientists, too, have long praised the plant for its water-resistant and self-cleaning properties. For years they have tried to mimic its structure.
