Surfaces that can passively mitigate ice accretion have recently attracted significant interest as an alternative to cost-intensive, active, de-icing technologies. After decades of research, several different approaches that can prevent the accretion of certain types of ice have been developed. The commercial applicability of these approaches, however, remains limited because of issues with coating durability, and because typically different kinds of icing typically require different mitigation strategies. This review classifies coatings that mitigate ice accretion into three categories based on their intended functions: surfaces that facilitate the detachment of accreted ice (ice shedding), surfaces that delay the accretion of ice (anti-icing), and surfaces that resist snow accretion (snow repellency). Next, we describe multiple coatings that have been developed thus far to achieve each of these functions, including their working principles, ease of scalability, and durability. We also discuss the current challenges associated with the laboratory testing and performance evaluation of different coatings.

作为成本密集型、主动式除冰技术的替代品，可以被动减轻积冰的表面最近引起了极大的兴趣。经过数十年的研究，已经开发出几种不同的方法可以防止某些类型的冰积聚。然而，这些方法的商业适用性仍然有限，因为涂层耐久性问题，并且因为通常不同类型的结冰通常需要不同的缓解策略。这篇综述根据其预期功能将减缓积冰的涂层分为三类：促进积冰分离的表面（冰脱落）、延缓积冰的表面（防结冰）和抗积雪的表面。防雪）。下一个，我们描述了迄今为止为实现这些功能而开发的多种涂层，包括它们的工作原理、易于扩展性和耐用性。我们还讨论了当前与不同涂层的实验室测试和性能评估相关的挑战。
