What Materials are Used in Nanocoatings for Self-Cleaning Lenses?
Common materials used in nanocoatings include titanium dioxide (TiO2), silicon dioxide (SiO2), and various fluorinated compounds. Titanium dioxide is particularly notable because it not only creates a hydrophobic surface but also exhibits photocatalytic properties. When exposed to UV light, TiO2 can break down organic molecules, further aiding in the self-cleaning process.
