Abstract

AbstractThe hydrophobic silica nanoparticles have been widely used in the fabrication of superhydrophobic surfaces. In this study, we prepared superhydrophobic coating using hydrophobic SiO2 nanoparticles by facile dip coat technique. After that, a layer of cyanoacrylate adhesive was applied to improve the durability of the superhydrophobic coating. Finally, the coating was annealed at 200 °C for 10 min. A water drop on prepared superhydrophobic coating showed contact angle ≈173° and sliding angle ≈1°. The prepared superhydrophobic coating revealed self‐cleaning behavior for more than 2 years. This approach can be useful for fabrication of superhydrophobic coating for practical industrial application including solar panel, windows glass, vehicle glass and fabrics, and so on.
