How Does the Lotus Leaf Effect Work?

The lotus leaf effect relies on two key factors: surface roughness and chemical composition. The surface of a lotus leaf is covered with microscopic bumps and nanostructures that create a rough texture. This multi-scale roughness, combined with the presence of a hydrophobic waxy coating, minimizes the contact area between water droplets and the leaf surface. Consequently, water droplets easily roll off, demonstrating the self-cleaning properties of the leaf.
