Self-cleaning surfaces

Self-cleaning surfaces are materials that have been engineered to repel dirt, grime, bacteria, and other contaminants, making them easier to maintain and keep clean. These surfaces utilize various innovative technologies to achieve their self-cleaning properties. There are two primary mechanisms for self-cleaning surfaces: 1. **Lotus Effect**: Inspired by the leaves of the lotus flower, this effect relies on micro- and nano-structures on the surface that create a high contact angle for water droplets.
