Superhydrophobic Coatings: Wet‐Style Superhydrophobic Antifogging Coatings for Optical Sensors (Adv. Mater. 34/2020)

In article number 2002710, Dong-Pyo Kim, Hyomin Lee, and co-workers report a wet-style superhydrophobic coating that exhibits excellent optical properties under a variety of environmental challenges. This coating for optical sensors is prepared by pattern transferring low-surface-energy microstructures onto a polymer–silica nanocomposite. The polymer–silica nanocomposite guides water molecules to preferably condense into and suppress reflection, while the low-surface-energy microstructure enables the coating to exhibit self-cleaning properties.
