Studies on fabricating robust superhydrophobic surfaces by a low-cost method have been rare, despite the recent demand for nature-inspired superhydrophobic surfaces including self-healing ability in various industrial applications. Herein, we propose a fabrication method for self-healable, robust superhydrophobic nanocomposite films by facile solution-processed spray coating and UV curing. The components of the coating solution include functionalized hydrophobic silica nanoparticles for producing high roughness hierarchical textured structures with low surface energy, and UV-crosslinkable v-POSS and bi-thiol hydrocarbon molecules to improve the film stability. As a result of the synergetic effect of the hydrophobic nanoparticles and UV-crosslinked polymeric compounds, the spray-coated and UV-cured nanocomposite films possess excellent superhydrophobicity (water contact angles > 150º) and high stability, in addition to self-healing abilities.

<p>Superhydrophobic surfaces (SHSs) require a combination of a rough nano- or microscale structured surface topography and a low surface energy. However, its superydrophobicity is easily lost, even under relatively mild mechanical abrasion, when the surface is mechanically weak. Here, we develop a method that significantly increases the mechanical durability of a superhydrophobic surface, by introducing a mesh layer beneath the superhydrophobic layer. The hardness, abrasion distance, flexibility and water-jet impact resistance all increase for the commercially available Ultra-ever Dry superhydrophobic coating. This is attributed to the increased mechanical durability offered by the mesh, whose construction not only increases the porosity of the SHS coating but acts as a third, larger structure, so that the superhydrophobic layer is now composed of a three-level hierarchical structure: the mesh, micropillars and nanoparticles.</p>
