Removing sticky droplets and making super repellent surfaces

Super-repellent surfaces lose their repellent properties when condensation occurs, either under low temperatures or high humidity conditions. A new surface has been developed, combining pyramidal microstructures with a nano-sized roughness on top, that maintains its super-repellent properties at all conditions.
