MIT News  November 1, 2018 Omniphobic surfaces can fail during condensation. Researchers at MIT have developed a nanostructured surface that consists of isolated reentrant cavities with a pitch on the order of 100 nm to prevent droplets from nucleating and spreading within all structures. They developed a model to guide surface design and subsequently fabricated and tested these surfaces with various liquids. They demonstrated repellency to 10 °C below the dew point and showed durability over 3 weeks. The work provides important insights for achieving robust, omniphobic surfaces…read more.
