Preparation and Application of Low‐Energy Consumption Aircraft Anti‐Icing Coatings: A Mini‐Review

Icing is a critical challenge during an aircraft's operational life, degrading aerodynamic performance, impairing sensors, and compromising flight safety. Most aircraft rely on thermal anti‐icing systems, but rising power demands from advanced electronics highlight the need for more energy‐efficient solutions. Passive anti‐icing technologies, using surface properties to reduce ice adhesion or delay condensation without external energy, offer a promising alternative. These approaches, such as micro/nanostructured surfaces and low‐ice‐adhesion coatings, can complement active systems and significantly cut energy use. However, much current research focuses on wind turbines and power lines, where icing conditions differ from aviation environments, limiting direct applicability. This paper reviews the icing process, interfacial mechanisms, fabrication methods, and performance of passive anti‐icing surfaces, along with durability assessment and aviation‐specific applications. It aims to build confidence among aviation engineers and guide material scientists in developing tailored, reliable solutions for aircraft.
