Self-cleaning surfaces modeled after lotus leaves

Definition

Self-cleaning surfaces modeled after lotus leaves refer to materials that mimic the natural properties of lotus leaves to repel dirt and water, keeping them clean without the need for manual cleaning or chemical agents. This phenomenon is known as the 'lotus effect,' where micro- and nano-structures on the leaf's surface cause water droplets to bead up and roll off, carrying away dirt particles. Such innovations have significant implications for sustainability and innovation, particularly in reducing the need for harsh cleaning agents and conserving water.
