In this section, we will explore three common methods used to create self-cleaning surfaces: nanostructured coatings, photocatalysis, and natural inspiration.

Nanostructured Coatings

Nanostructured coatings are widely employed to create self-cleaning surfaces. By modifying the surface at the nanoscale, either through the incorporation of nanoparticles or by creating a hierarchical structure, these coatings enhance the self-cleaning properties of surfaces (IntechOpen). The hierarchical structure or nanoparticle presence alters the surface’s physical and chemical properties, allowing it to repel water and prevent the adherence of dirt and contaminants.

These coatings can be applied to various materials, including glass, metal, and ceramics, making them highly versatile.
