Facile fabrication of fluorinated SiO 2 /acrylic-polyurethane superhydrophobic coatings with enhanced anti-icing and corrosion resistance for marine environments

This is the authors' abstract. We don't add key points for this paper.

Conventional superhydrophobic coatings often exhibit significant limitations, including poor durability under low-temperature and unstable long-term anti-corrosion performance, which compromises their effectiveness in practical applications. This study prepares a superhydrophobic coating composed of fluorinated silica and acrylic-polyurethane via a simple spray process. The unique micro–nano structure on the coating surface generates a notable and stable air cushion effect, extending the freezing time of droplets and reducing the ice adhesion strength between the surface and ice. Additionally, the air pocket serves as a barrier, significantly enhancing the long-term corrosion resistance of the coating. The coating developed in this study provides new ideas for candidate anti-icing and anti-corrosion materials for ships.
