Facile designing a superhydrophobic anti-icing surface applied for reliable long-term deicing

摘要

While superhydrophobic coatings have shown promise as potential anti-icing coatings,the surface roughness of these coatings is prone to damage during repeated icing-deicing cycles.Herein,two kinds of superhydrophobic anti-icing coatings are prepared from organic resin and micro-nano particles using two strategies,and their excellent anti-icing properties are also investigated.However,superhydrophobic surface I(SF1),prepared by first strategy,cannot be used for extended periods of time due to irreversible damage to the surface roughness during the icing-deicing process.Finite element simulations and experimental studies are preformed to investigate the fatal issue of such roughness damage.In contrast,the anti-icing properties of superhydrophobic surface II(SF2),prepared by second strategy,can easily regain through a simple sandpaper abrasion treatment even the surface roughness was damaged during the icing-deicing process.These exploratory results and SF2 preparation strategy provide a facile design of anti-icing coating,and the derived restorable anti-icing coating is expected to be useful for a wide application.
