Abstract

Icephobic surfaces have a critical footprint on human daily lives in cold climates ranging from aviation systems and infrastructures to energy systems. However, 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 ice adhesion strength (~20-100 kPa) and subsequent ice accretion, low long-term mechanical and environmental durability, and high production cost have restricted their applications. Here, we cast fundamentals of a new physical concept called stress-localization to develop icephobic surfaces with ice adhesion in order of 1 kPa and exceptional mechanical, chemical and environmental durability.
