Significance: Among various anti-icing conditions, cold and humid environments are the most difficult to tackle. Although photothermal materials have been used to increase surface temperature for delaying freezing, severe condensation under cold and humid environments causes increased reflection, resulting in lower temperature rise and eventually condensate freezing. Ideal passive anti-icing surfaces should remove condensed water immediately, leaving no water for freezing. Herein, a condensate self-removing solar anti-icing/frosting surface is developed. With optimum hierarchical micro/nanostructures, it has excellent photothermal capability to elevate surface temperature and simultaneously can shed off condensed water effectively via coalescence-induced droplet jumping, providing continuously refreshed dry surface for sunlight absorption to maintain the elevated temperature under challenging environmental conditions, where condensation and fogging would otherwise be strongly promoted.
