在寒冷的气候中，憎冰表面对人类的日常生活有着至关重要的影响，其用途从航空系统和基础设施到能源系统。然而，为低温应用创建这些表面仍然很困难。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，高的冰粘附强度（约20-100 kPa）和随后的积冰、低的长期机械和环境耐久性以及高的生产成本限制了它们的应用。在这里，我们奠定了一个新的物理概念的基础，称为应力局部化，以开发冰附着力在1千帕和特殊的机械，化学和环境耐久性的憎冰表面。
Icephobic surfaces have daily critical impact on human lives in cold climates, with uses ranging from aviation systems and infrastructure to energy systems. However, creation of these surfaces for low-temperature applications remains difficult. Non-wetting, liquid-infused and hydrated surfaces have inspired routes for development of icephobic surfaces. However, high ice adhesion strength (approximate to 20-100 kPa) and subsequent ice accretion, low long-term mechanical and environmental durability and high production cost have restricted their applications. Here, we lay the fundamentals of a new physical concept called stress-localization to develop icephobic surfaces with ice adhesion in the order of 1 kPa and exceptional mechanical, chemical and environmental durability.
