Smart coatings are advanced materials that can change their properties in response to environmental stimuli, such as temperature, moisture, or light. These coatings can provide benefits like self-cleaning surfaces, anti-corrosion protection, and enhanced durability. They are often used in various industries, including automotive, aerospace, and construction, to improve the performance and longevity of products. One common type of smart coating is thermochromic paint, which changes color with temperature fluctuations. Another example is self-healing coatings, which can repair minor scratches and damage automatically. These innovations are paving the way for more efficient and sustainable materials in everyday applications.
