Lotus effect - Wikipedia
网页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.
Lesson Superhydrophobicity — The Lotus Effect
网页Describe situations in which a superhydrophobic lotus-effect surface would be useful. Explain the difference between Cassie-Baxter and Wenzel wetting and how it applies to superhydrophobic surfaces. Demonstrate the transition between …
Theoretical Explanation of the Lotus Effect: Superhydrophobic …
网页The lotus effect is attributed to a surface structure that is covered with needle-shaped wax tubes, and the remaining surface allows invasion of the water droplet and enlarges the interaction with water.
Superhydrophobicity in perfection: the outstanding properties of …
网页2011年3月10日 · Lotus leaves have become an icon for superhydrophobicity and self-cleaning surfaces, and have led to the concept of the ‘Lotus effect’. Although many other plants have superhydrophobic surfaces with almost similar contact angles, the lotus shows better stability and perfection of its water repellency.
Nature–Inspired self–cleaning surfaces: Mechanisms, modelling, …
网页2020年3月1日 · We will introduce six nature-inspired self-cleaning mechanisms: The Lotus-effect, superhydrophobic-induced droplet jumping, superhydrophobic-induced unidirectional movement of water droplet, underwater-superoleophobic-based self-cleaning, slippery-based self-cleaning, and dry self-cleaning.
Lotus Leaf: Lotus Effect - SpringerLink
网页For lotus leaves in nature, the lotus effect causes raindrops to roll easily across the leaf surfaces and remove any dirt on them. The lotus effect is caused by the combination of two features of the leaf surface: waxiness and a hierarchical, dual-scale architecture.
Lotus Effect - SpringerLink
网页Definition. Lotus effect is surface roughness–induced superhydrophobicity and self-cleaning. These surfaces have a water contact angle (CA) larger than 150° and a low (usually <5°) contact angle hysteresis. These surfaces also exhibit low drag during fluid flow.
Self-Cleaning Materials: Lotus Leaf-Inspired Nanotechnology
网页2008年8月1日 · Wilhelm Barthlott of the University of Bonn in Germany, discoverer and developer of the “lotus effect,” has a vision of a self-cleaning Manhattan, where a little rain washes the windows and...

网页2016年1月1日 · The study reveals the secret of lotus leaf, which, not surprisingly, attributes to its combination of surface roughness and chemical substances. Hydrophobicity and self-cleaning of lotus leaf are believed as a mechanism to resist harmful microorganism bounding to the leaf surface, since water is usually required for the germination.
