积冰对一系列商业和居民活动产生不利影响。通常认为从表面去除冰所需的力与结冰面积成比例。这对用于具有大表面积的结构（例如电力线或船体）的疏冰涂层的使用赋予了可扩展性限制。我们描述了一类材料，表现出低的界面韧性与冰，导致在系统中所需的力，以消除大面积的冰（几平方厘米或更大）都低，独立的结冰面积。我们进一步证明，由这种材料制成的涂层允许冰仅通过自重容易地从大面积（类似于1平方米）脱落。
Ice accretion has adverse effects on a range of commercial and residential activities. 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. We 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 (a few square centimeters or greater) are both low and independent of the iced area. We further demonstrate that coatings made of such materials allow ice to be shed readily from large areas (similar to 1 square meter) merely by self-weight.
