The term "icephobicity" has emerged in the literature recently. An extensive discussion took place on whether the icephobicity is related to the superhydrophobicity, and the consensus is that there is no direct correlation. Besides the parallel between the icephobicity and superhydrophobicity for water/ice repellency, there are similarities on other levels including the hydrophobic effect/hydrophobic interactions, mechanisms of protein folding and ice crystal formation. In this paper, we report how ice adhesion is different from water using force balance analysis, and why superhydrophobic surfaces are not necessary icephobic. We also present experimental data on anti-icing of various surfaces and suggest a definition of icephobicity, which is broad enough to cover a variety of situations relevant to de-icing including low adhesion strength and delayed ice crystallization and bouncing.
“憎冰性”一词最近在文献中出现。关于憎冰性是否与超疏水性相关展开了广泛讨论，目前的共识是两者没有直接关联。除了憎冰性和超疏水性在拒水/拒冰方面的相似之处外，在其他层面也存在相似性，包括疏水效应/疏水相互作用、蛋白质折叠机制和冰晶形成机制。在本文中，我们通过力平衡分析报告了冰附着力与水附着力的差异，以及超疏水表面为何不一定具有憎冰性。我们还展示了各种表面防冰的实验数据，并提出了憎冰性的定义，该定义足够宽泛，能够涵盖与除冰相关的各种情况，包括低粘附强度、延迟冰晶形成和弹跳。
