简介
Enabling surfaces with passive anti-icing properties is an emerging, facile, economical, and energy-saving strategy to mitigate the harm caused by ice accretion. However, the combination of icephobicity and robustness remains a daunting challenge. Herein, we present an ultra-robust transparent icephobic coating with high toughness, strong substrate adhesion, and self-healing capability. Hydrophobicity, smoothness, and softness of the coating guarantee low ice adhesion strength. By incorporating a spongy structure, the ice adhesion strength of the coating is lowered further down to 26.7 ± 1.1 kPa. Importantly, the coating exhibits high toughness, strong adhesion to the substrate, and self-healing capability due to the presence of multiple hydrogen bonding. Consequently, the coating maintains its icephobicity after 35 icing/deicing cycles and 600 abrasion cycles, is resilient to delamination, and is able to heal and …
