See Through the Fog

According to the journal Applied Materials and Interfaces, scientists from Quebec City’s Université Laval have recently developed the world’s first permanent anti-fog coating for transparent glass or plastic surfaces. To make the coating, the researchers applied the hydrophobic compound polyvinyl alcohol on top of several layers of silicon via an atmospheric plasma process.
Unlike other commercially-available anti-fog coatings that make claims of permanence, the new technology will endure repeated abuse without requiring reapplication. Initial applications target eyewear, which is good news for anyone tired of their glasses or diving masks fogging up. Perhaps we’ll also see bathroom mirrors with the new anti-fog coating before long.
