Effects of Surface Roughness on the Anti-icing Performance of Superhydrophobic Coatings

Ice adhesion and accretion is a serious threaten for the safety and efficiency in the field of transportation, electricity and aviation, etc., and it is of great application significance to develop the anti-icing technique. At present, the most promising method for anti-icing is employing hydrophobic coatings. This paper introduces the ways to fabricate superhydrophobic coatings and illustrates the correlation between the hydrophobic nature of a coating and its anti-icing performance. The effects of surface roughness on the ice coating behaviors have been mainly discussed,and problems remained in development of anti-icing coatings was pointed out. Finally, the prospective tendency of anti-icing coating is proposed based on the current challenges.
