摘要
Superhydrophobic coating with applicable transmittance was synthesized by simple UV-curable method which was likely suitable for large-scale production. The super-hydrophobicity was derived from the component containing modified polyhedral oligomeric silsesquioxanes which was chosen for low free energy and the potential to form hierarchical structure. The coating adhesion could reach the highest level by strip tape peel test. Compared to the UV-cured commercial coatings, the coating adhesion is enhanced by at least two levels. Super-hydrophobicity was preserved after long duration of water droplet impact, while water contact angle decreased slightly after sand impact due to partial damage of hierarchical structure. The coating can resist chemical corrosion by acid solution (HCl), base solution (NaOH) and salt solution (NaCl). The coating with water repellence function, adequate transmittance, and good mechanical and chemical stability is of great interest for practical outdoor applications.
