Abstract

Abstract : We introduce and present the fundamentals of stress-localization concept to minimize adhesion of ice or other contaminants on a surface. Abstract : 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 (∼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.
