In this study, KH-570 was used to modify the surface of nano-SiO2 to obtain functionalized nano-SiO2, and then fluorine-containing acrylic monomer was grafted onto the surface of nanomaterials. This study effectively improved the surface roughness of the coating, and SiO2 particles can fully fill the gaps of the coating, thereby improving the hydrophobicity and anticorrosion ability of the coating.
