Next, we will discuss how the force required to remove ice from a surface is typically considered to scale with the iced area. This imparts a scalability limit to the use of icephobic coatings for structures with large surface areas, such as power lines or ship hulls. I will then describe a class of materials that exhibit a low interfacial toughness with ice, resulting in systems for which the forces required to remove large areas of ice (few cm2 or greater) are both low and independent of the iced area. Coatings made of such materials allow ice to be shed readily from large areas (~1m2) merely by self-weight.
