Superhydrophobic surface coatings with high static water contact angle (>150°) have been receiving tremendous attention in recent years. The applications of superhydrophobic coatings are diverse due to their unique water-repellency, self-cleaning ability, and anti-biofouling property. Various methods have been proposed to fabricate superhydrophobic surfaces mimicking the lotus surface structure, including lithographic patterning, plasma etching, electrochemical deposition, and chemical vapor deposition. However, these methods often require harsh synthetic conditions and complex fabrication techniques. Furthermore, the poor mechanical stability of superhydrophobic coatings formulated on the surface is generally another limitation in their widespread applications. Herein we demonstrate on a one-step facile spray-coating technique to prepare a superhydrophobic surface coated with perfluorinated silica/silyl-modified methacrylate nanocomposites. The superhydrophobic surface coatings are characterized in term of water contact angles, wetting hysteresis, and the surface roughness/morphology. Futhermore, abrasion resistance of the fabricated superhydrophobic coatings was evaluated by a home-made scratch tester, which was composed of a piece of sandpaper and weights of different masses.
