Remarkable progress has been made in surface icephobicity in the recent years. The mainstream standpoint of the reported antiicing surfaces yet only considers the ice-substrate interface and its adjacent regions being of static nature. In reality, the local structures and the overall properties of ice-substrate interfaces evolve with time, temperature and various external stimuli. Understanding the dynamic properties of the icing interface is crucial for shedding new light on the design of new anti-icing surfaces to meet challenges of harsh conditions including extremely low temperature and/or long working time. This article surveys the state-of-the-art anti-icing surfaces and dissects their dynamic changes of the chemical/physical states at icing interface. According to the focused critical ice-substrate contacting locations, namely the most important ice-substrate interface and the adjacent regions in the substrate and in the ice, the available anti-icing surfaces are for the first time re-assessed by taking the dynamic evolution into account. Subsequently, the recent works in the preparation of dynamic anti-icing surfaces (DAIS) that consider time-evolving properties, with their potentials in practical applications, and the challenges confronted are summarized and discussed, aiming for providing a thorough review of the promising concept of DAIS for guiding the future icephobic materials designs.
近年来，在表面抗冰性方面取得了显著进展。然而，报道的抗冰表面的主流观点仅考虑了冰-基底界面及其相邻区域处于静态性质。实际上，冰-基底界面的局部结构和整体性质随时间、温度和各种外部刺激而演变。了解冰界面的动态特性对于揭示新的抗冰表面设计至关重要，以应对包括极低温度和/或长时间工作在内的恶劣条件的挑战。本文综述了最新的抗冰表面，并剖析了它们在冰界面处化学/物理状态的动态变化。根据聚焦的关键冰-基底接触位置，即最重要的冰-基底界面以及基底和冰中的相邻区域，首次考虑动态演变重新评估了现有的抗冰表面。随后，总结和讨论了考虑时间演变特性的动态抗冰表面（DAIS）的最新制备工作，及其在实际应用中的潜力，以及面临的挑战，旨在为 DAIS 的有前途的概念提供全面的综述，以指导未来的冰斥材料设计。
