Verification of Icephobic/Anti-icing Properties

Icephobic/Anti-icing Properties were verified by sliding angle (SA) and High-speed photography. It was found that single and successive water droplets could rebound on the superhydrophobic surface and roll off at a tilt angle larger than 30°under an extremely condensing weather condition (10 °C and relative humidity of 8590%). In addition, the superhydrophobic surface showed a strong icephobic property, the ice adhesion on this surface was only 13% of that on the superhydrophilic surface, though they had a similar nano/microtopological structure. Moreover, this superhydrophobic surface displayed an excellent durability of the icephobic property. The ice adhesion only increased to 20% and 16% of that on the superhydrophobic surface after the surface was undergone 20 icing/ice-breaking cycles and 40icing/ice-melting cycles.

Superhydrophobicity of Natural and Artificial Surfaces under Controlled Condensation Conditions

the superhydrophobic surface under controlled condensation conditions calculated and experimental results indicate that the temperature difference between surface temperature andthe dew point during measurement is essential to the occurrence of water condensation. The loss of water repellency that usually appears under low temperature and high humidity conditions is proved to be reversible, showing a transition of the equilibrium state between Wenzel and Cassie-Baxter.
