Creating anti-icing surfaces has proven to be a challenging task. With such a wide range of impacting parameters it is important to quantify ones with a large effect. Water solidification mechanisms play a fundamental role in designing anti-icing surfaces. In this Review Article, we will consider the effects of surface roughening on the mechanisms of nucleation and ice growth to show how surface roughening can be an alternative to overcome the limitations of icing of superhydrophobic coatings and surfaces. The results from various studies of anti-icing properties of superhydrophobic surfaces are reviewed and expanded to incorporate water solidification mechanisms to provide a more comprehensive approach to the design of anti-icing surfaces. The literature within this review shows that by applying the necessary roughness to either hydrophilic or hydrophobic surfaces and adjusting the surface topography, we can significantly suppress ice nucleation on various surfaces.
事实证明，制造防冰表面是一项具有挑战性的任务。由于影响参数范围如此广泛，量化具有较大影响的参数非常重要。水凝固机制在防冰表面设计中起着基础性作用。在这篇综述文章中，我们将考虑表面粗糙化对成核和冰生长机制的影响，以展示表面粗糙化如何能够作为一种替代方法来克服超疏水涂层和表面结冰的局限性。对超疏水表面防冰性能的各种研究结果进行了综述和扩展，纳入了水凝固机制，以便为防冰表面设计提供更全面的方法。这篇综述中的文献表明，通过对亲水或疏水表面施加必要的粗糙度并调整表面形貌，我们可以显著抑制各种表面上的冰核形成。
