摘要/Abstract

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 of polyacrylic acid (PAA) based resin material is synthesized as the coat-ing-matrix. Then the functionally-modified SiO2 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 ?C comparing with that (?13.83 ?C) 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.
