Excellent Dynamic Non-Wetting Performance Induced by Asymmetric Structure at Low Temperatures: Retraction Actuation and Nucleation Inhibition.

ABSTRACT: Asymmetric structures have exhibited significant advantages in regulating wetting behavior. Nevertheless, the influence of this unique structural feature on anti-icing performance remains to be further explored. In this work, static/dynamic anti-icing performance is investigated on the asymmetric superhydrophobic structures fabricated by micro-milling combined with electrodeposition. Notably, although the reduction of the degree of asymmetry increases the droplet adhesion force by augmenting the solid-liquid interface, asymmetric structures can still enable the droplet to bounce off the surface through the horizontal Laplace force generated by the contact angle difference between the two sides of the droplet. On this basis, a dynamic behavior criterion for the droplet to detach from the su
