Prompt Description

Generate a schematic diagram illustrating the self-cleaning mechanism of a superhydrophobic self-cleaning coating. This figure is intended for use in a scientific research paper. The diagram should primarily depict the self-cleaning principle, including a rectangular silver-gray iron substrate coated with a gray-white superamphiphobic (superhydrophobic and superoleophobic) coating. Black and brown particles (representing dust, sand, and other contaminants) are adhered to the coating. Water droplets rolling across the surface (with a contact angle greater than 150 degrees, appearing as nearly spherical droplets) should be shown picking up and absorbing the dust particles. As the water droplets roll down the surface, they remove the contaminants, achieving the self-cleaning effect. Please generate this figure according to the standards for scientific illustrations, with clear and concise colors, and labeled explanations for each component.
