You have just watched a video broadcasting the self-cleaning and water repellent properties on a leaf surface (lotus effect). What you have seen in the video occurs due to a specific surface phenomenon called superhydrophobicity. It is known that lotus leaf behaves as a super hydrophobic surface. So, Superhydrophobicity is sometimes referred to as the lotus effect. Let us now analyze the characteristics and applications of this phenomenon.
Superhydrophobic surfaces contain micro protrusions that are coated by nano waxy materials. When water droplets are poured, they will sit on the tips of the hydrophobic protrusion. The combined structure will trap a layer of air between the surface and t...
