Nanoscale coatings are thin layers of material that are applied at the nanoscale, typically measuring between 1 to 100 nanometers in thickness. These coatings can enhance the properties of surfaces, such as making them more resistant to scratches, corrosion, or bacteria. They are used in various industries, including electronics, healthcare, and automotive, to improve performance and durability. The unique characteristics of nanoscale coatings arise from their small size, which allows for increased surface area and altered chemical properties. For example, coatings made from nanoparticles can provide antimicrobial effects, while those designed for optical applications can improve light transmission.
