摘　　要：This work is focused on the development of a facile strategy to fabricate superhydrophobic coatings,which are characterized with lower water freezing temperature and lower ice adhesion.First,a kind o f polyacrylic acid(PAA)based resin material is synthesized as the coating-matrix.Then the functionally-modified S i02 nanoparticles are added to regulate the surface morphology for obtaining the ideal superhydrophobicity.The as-synthesized resin coatings possess strong bonding strength with metal substrate,and the surface hierarchical morphologies(10 wt% SiO2 nanoparticles)induce the robust superhydrophobicity with a high water contact angle of 152°.Also,the superhydrophobic coatings are endowed with high icephobicity,and the freezing temperature of reference water droplet is reduced to-20.33℃ comparing with that(-13.83℃)on the coatings without additive nanoparticles.Furthermore,the ice adhesion strength on the superhydrophobic coatings is only 250 kPa,exhibiting the great ability of ice repellence.
