Self-Cleaning Coatings: These use nanomaterials to create superhydrophobic surfaces that repel water and dirt. Antimicrobial Coatings: Incorporate nanoparticles like silver to kill bacteria and other pathogens. Anti-Corrosion Coatings: Use nanostructured layers to protect metals from oxidation and corrosion. Thermochromic Coatings: Change color in response to temperature variations. Electrochromic Coatings: Alter their optical properties when an electrical voltage is applied.
