Ice formation and accumulation on surfaces has a negative impact in many different sectors and can even represent a potential danger. In this review, the latest advances and trends in icephobic coatings focusing on the importance of their durability are discussed, in an attempt to pave the roadmap from the lab to engineering applications. An icephobic material is expected to lower the ice adhesion strength, delay freezing time or temperature, promote the bouncing of a supercooled drop at subzero temperatures and/or reduce the ice accretion rate. To better understand what is more important for specific icing conditions, the different types of ice that can be formed in nature are summarized. Similarly, the alternative methods to evaluate the durability are reviewed, as this is key to properly selecting the method and parameters to ensure the coating is durable enough for a given application. Finally, the different types of icephobic surfaces available to date are considered, highlighting the strategies to enhance their durability, as this is the factor limiting the commercial applicability of icephobic coatings.
表面结冰和积冰在许多不同领域都有负面影响，甚至可能构成潜在危险。在这篇综述中，讨论了疏冰涂层的最新进展和趋势，重点关注其耐久性的重要性，试图为从实验室到工程应用铺平道路。疏冰材料预计可降低冰的粘附强度、延迟冻结时间或温度、促进过冷液滴在零下温度下弹跳和/或降低积冰速率。为了更好地理解在特定结冰条件下什么更重要，总结了自然界中可能形成的不同类型的冰。同样，对评估耐久性的替代方法进行了综述，因为这是正确选择方法和参数以确保涂层在给定应用中具有足够耐久性的关键。最后，考虑了迄今为止可用的不同类型的疏冰表面，强调了提高其耐久性的策略，因为这是限制疏冰涂层商业适用性的因素。
