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.

Constructing superhydrophobic surfaces by simple and low-cost methods remains a challenge in achieving the large-scale commercial application of superhydrophobic materials. Herein, a facile two-step process is presented to produce a self-healing superhydrophobic surface on wood to improve water and mildew resistance. In this process, the natural hierarchical structure of wood is firstly modified by sanding with sandpaper to obtain an appropriate micro/nano composite structure on the surface, then a fluoroalkylsilane/silica composite suspension is cast and dried on the wood surface to produce the superhydrophobic surface. Due to the full use of the natural hierarchical structure of wood, the whole process does not need complicated equipment or complex procedures to construct the micro/nano composite structure. Moreover, only a very low content of inorganic matter is needed to achieve superhydrophobicity. Encouragingly, the as-obtained superhydrophobic surface exhibits good resistance to abrasion. The superhydrophobicity can still be maintained after 45 abrasion cycles under the pressure of 3.5 KPa and this surface can spontaneously recover its superhydrophobicity at room temperature by self-healing upon damage. Moreover, its self-healing ability can be restored by spraying or casting the fluoroalkylsilane/silica composite suspension onto this surface to replenish the depleted healing agents. When used for wood protection, this superhydrophobic surface greatly improves the water and mildew resistance of wood, thereby prolonging the service life of wood-based materials.

Bioinspired superhydrophobic surfaces have attracted great interest from fundamental research to engineering applications. The stability, design, and regulation of superhydrophobicity, especially in a submerged environment, have been one of the main focuses of recent efforts. This review is dedicated to illustrating the fundamental characteristics of underwater superhydrophobicity, introducing novel and effective strategies for robust design and regulation, and to providing an overview of the state-of-the-art engineering applications in drag reduction and cavitation/boiling control. First, the underlying mechanisms of wetting transition on superhydrophobic surfaces submerged underwater induced by physical phenomena including pressurization, air diffusion, fluid flow, and condensation are reviewed. The influence of the closed/open state of entrapped air cavities is differentiated. Landmark experiments demonstrating wetting transition mechanisms are surveyed. Then, novel strategies for designing robust superhydrophobic surfaces are summarized, including hierarchical, reentrant, lubricant-infused, and mechanically durable structures. Moreover, strategies for superhydrophobicity regulation are introduced, which are classified into two types: self-healing and dewetting, based on the failure regime (surface damage or meniscus collapse). The current state-of-the-art engineering applications in drag reduction and cavitation/boiling control are comprehensively reviewed. Last but not least, remaining challenges for future research are given at the conclusion.
