The lotus effect has inspired many types of liquid repelling surfaces, but tiny water droplets stick to lotus leaf structures. Now, researchers have developed the first nano/micro-textured highly slippery surfaces able to outperform lotus leaf-inspired liquid repellent coatings, particularly in situations where the water is in the form of vapor or tiny droplets.
