Multifunctional coating (VIDEO) Optica This video is under embargo. Please login to access this video. Caption To create the new multifunctional coating system, the researchers used a polymer coating that prevents fogging by acting as a water reservoir. They combined the antifog film with nanostructures that create an anti-reflective effect together while being water permeable.
