The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of Nelumbo, the lotus flower. [1] Dirt particles are picked up by water droplets due to the micro- and nanoscopic architecture on the surface, which minimizes the droplet's adhesion to that surface.
The contact angles of a water droplet on an ultrahydrophobic material exceed 150°. [1] This is also referred to as the lotus effect, after the superhydrophobic leaves of the lotus plant. A droplet striking these kinds of surfaces can fully rebound like an elastic ball. [2]
The leaves of Nelumbo are highly water-repellent (i.e. they exhibit ultrahydrophobicity) and have given the name to what is called the lotus effect. [3] Ultrahydrophobicity involves two criteria: a very high water contact angle between the droplet of water and the leaf surface, and a very low roll-off angle. [4]
A water drop on a lotus plant leaf. Superhydrophobic surfaces, such as the leaves of the lotus plant, are those that are extremely difficult to wet. The contact angles of a water droplet exceeds 150°. [6] This is referred to as the lotus effect, and is primarily a chemical property related to interfacial tension, rather than a chemical ...
Water drop on glass, with reflection below. A water drop on a lotus leaf surface showing contact angles of approximately 147°. Contact angles are extremely sensitive to contamination; values reproducible to better than a few degrees are generally only obtained under laboratory conditions with purified liquids and very clean solid surfaces.
The modest 440-piece Flower Bouquet is made up of an assortment of brick-built flower staples, including roses, daisies and snapdragons, none of them requiring even a drop of water. Lego £54.99 ...
Lotus leaves have a typical contact angle of , ultra low water adhesion due to minimal contact areas, and a self cleaning property which is characterised by the Cassie-Baxter equation. [13] The microscopic architecture of the Lotus leaf means that water will not penetrate nanofolds on the surface, leaving air pockets below.
