从航空系统和基础设施到能源系统，憎冰表面在人类日常生活中具有重要的影响，但为低温应用创造这些表面仍然是难以捉摸的。非润湿的、液体注入的和水合的表面启发了用于开发疏冰表面的途径。然而，冻结温度高、冰粘附强度高和随后的积冰、机械耐久性低和生产成本高限制了它们的实际应用。在这篇综述中，我们提供了一个全面的定义，通过热力学，传热和力学的冰/水-材料界面和阐明物理为基础的路线，通过纳米尺度可以帮助实现特殊的憎冰表面。根据守恒定律，数学模型的开发，准确地预测冰的增长率在各种基板和风力条件。通过冰-憎冰材料界面处的断裂物理学，我们铸造了一种用于冰粘附力测量的标准方法，该方法有可能消除来自不同实验室的冰粘附力报告之间的差异。为了确保憎冰表面的长期性能，需要定义耐久性指标。我们提供标准的方法来检测憎冰表面的机械、化学和环境耐久性。在这篇综述中，在开发的综合框架中，对最先进的憎冰表面的性能进行了比较，并突出了该领域的主要不足之处。(C)2019爱思唯尔B.

Icephobic surfaces have a critical footprint on human daily lives ranging from aviation systems and infrastructures to energy systems, but creation of these surfaces for low-temperature applications remains elusive. Non-wetting, liquid-infused and hydrated surfaces have inspired routes for development of icephobic surfaces. However, high freezing temperature, high ice adhesion strength and subsequent ice accretion, low mechanical durability, and high production cost have restricted their practical applications. In this review, we provide a comprehensive definition for icephobicity through thermodynamics, heat transfer and mechanics of ice/water-material interface and elucidate physic-based routes through which nano-scale could help to achieve exceptional icephobic surfaces. Based on conservation laws, mathematical models are developed that accurately predict ice growth rate on various substrates and wind conditions. Through physics of fracture at ice-icephobic material interface, we cast a standard method for ice adhesion measurement that has the potential to eliminate discrepancies between reported ice adhesion from different laboratories. To assure long-time performance of icephobic surfaces, durability metrics need to be defined. We provide standard methods to examine mechanical, chemical, and environmental durability of icephobic surfaces. In the developed comprehensive framework on icephobicity in this review, performance of state-of-the-art icephobic surfaces are compared and main deficiencies in this field are highlighted.
