The formation of ice on various technologies today poses serious safety risks. For example, if ice forms on the wing of an airplane before it takes off, the plane's lift will be greatly reduced and it can crash. Despite the need for anti-ice coatings, most state-of-the-art coatings allow water to freeze under moderate conditions (for example, a temperature less than <math>-5</math> degrees Celcius and a relative humidity greater than 50%).

There are two main approaches to creating icephobic materials. One approach is to create an extremely smooth surface with an extremely small contact hysteresis
