Icephobic surfaces, used as passive anti-icing materials, are in high demand due to the costs, damage, and loss of equipment and lives related to ice formation on outdoor surfaces. The proper design of icephobic surfaces is intertwined with the need for a profound understanding of ice formation processes and how ice propagates over a surface. Ice formation (ice nucleation) and interdroplet freezing propagation are processes that determine the onset of freezing and complete ice coverage on a surface, respectively. Evaluating the nature of these phenomena, along with their interactions with substrate and environmental factors, can offer a step toward designing surfaces having an improved icephobic performance. This review paper is organized to discuss ice nucleation and rate, preferable locations of nucleation, and favorable pathways of freezing (desublimation and condensation-freezing) on superhydrophobic surfaces. Furthermore, as the propagation of ice over a substrate plays a more deterministic role for the complete freezing coverage of a surface than that of ice formation, this review also elucidates possible mechanisms of ice propagation, theoretical backgrounds, and strategies to control this propagation using surface characteristics.
作为被动防冰材料的憎冰表面，由于室外表面结冰所涉及的成本、设备损坏以及人员伤亡等问题，其需求很高。憎冰表面的合理设计与深入理解结冰过程以及冰在表面的传播方式密切相关。结冰（冰核形成）和液滴间冻结传播分别是决定表面开始结冰和完全被冰覆盖的过程。评估这些现象的本质，以及它们与基底和环境因素的相互作用，可为设计具有改进憎冰性能的表面提供一个方向。这篇综述文章旨在讨论超疏水表面上的冰核形成及其速率、成核的优选位置以及有利的冻结途径（升华和冷凝冻结）。此外，由于冰在基底上的传播对表面完全冻结覆盖所起的作用比结冰更为关键，本综述还阐明了冰传播的可能机制、理论背景以及利用表面特性控制这种传播的策略。
