Nanotechnology inspired by lotus effect

Definition

Nanotechnology inspired by the lotus effect refers to the development of surfaces that mimic the self-cleaning properties of lotus leaves, which repel water and dirt due to their unique micro- and nanostructures. This principle is based on the observation that lotus leaves remain clean in muddy environments, thanks to their superhydrophobic surface, which is achieved through a combination of hydrophobic materials and intricate surface topography. The application of this technology can lead to innovations in various fields, including textiles, coatings, and building materials.
