Inspired by the poison dart frog skin that secretes functional liquid after

being stimulated, a liquid-infused double-layer surface (LDS) is designed

by integrating superhydrophobic layer with liquid-infused layer. Both layers

generate the wettability gradient to drive tiny condensed droplet into the

liquid-infused layer, and the liquid-infused layer would effectively lower the

freezing point for nonicing. Especially, the internal wetting transport ability

appears between both layers, greatly reducing icing possibility of the surface,

i.e., the tiny condensed droplets in the micropores can be transported to

liquid-infused layer with nonfrozen properties. Thus, the surface of LDS

thereby keeps superhydrophobic property for antiicing and antifrosting in a

long term. This design makes LDS achieve excellent antiicing and antifrosting

properties against cold environments with high humidity. And it may be

significant for such materials to be extended into some realms, e.g., antiicing

in aviation and power for long-term durability in cold and high moisture

environment.
