Prompting Interfacial Elastic Instability for Effective and Durable Icephobic Surfaces

open access: yesAdvanced Science, EarlyView.
To address the inherent trade‐off between icephobicity and the mechanical strength of icephobic materials, a new icephobic material design strategy is proposed by integrating fibrous construction frameworks and icephobic polymer. The structure prompts interfacial elastic instability and the subsequent undulatory interfacial stress at ice/solid ...
