An engineered surface unsticks sticky water droplets

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.
