Inspired by the features of natural pine needle, a superhydrophobic concave‐cone pillar surface (CCPS) is designed by using polymer via soft lithography and printing methods. CCPS has the characterizes of unique flexible performance and concave conical geometry to lower adhesion between liquid/ice–solid interfaces, thus as‐frozen ice droplet can be easily detached by tilting or a slight shear flow. Comparing to normal cone pillar surface, CCPS achieves excellent deicing ability, attributed to unique antipinning effect between ice and concave‐cone pillars, which is demonstrated by force characterization. This finding offers an insight into design of novel icephobic/anti‐icing surfaces and materials that can be extended into some applied realms for solving icing problems, e.g., transmission line, traffic road, aircraft wing, etc.

极度冰冷的松针启发式凹锥形柱阵列

受天然松针的特性启发，超疏水凹锥柱表面（CCPS）是通过使用聚合物通过软光刻和印刷方法设计的。CCPS具有独特的柔性性能和凹入的圆锥形几何形状的特征，可降低液/冰-固体界面之间的附着力，因此，冻结的冰滴很容易因倾斜或略有剪切流而脱落。与普通圆锥形支柱表面相比，CCPS具有出色的除冰能力，这归因于冰和凹锥支柱之间的独特抗钉扎效果，这通过力的表征得以证明。该发现提供了对新颖的防冰/防冰表面和材料的设计的见解，这些表面和材料可以扩展到一些解决冰冻问题的应用领域，例如输电线路，交通道路，飞机机翼等。
