“…20 While this method relies heavily on the adhesion of the coating to achieve stability. Dessouky et al 21 adopted different concentrations of functionalized silica (FS) nanoparticles and different polymers (i.e. epoxy, PU, polystyrene (PS), or poly(ethylene-covinyl acetate) (EVA)) to achieve one-step low-cost spraying method to fabricate uniform superhydrophobic coating without special equipment.…”

The biomimetic superhydrophobic surface derived from lotus effect is one of the hotspot issues in recent years and also a specific application case of biomimetic in modern industry. Based on the excellent characteristics of bionic superhydrophobic surface, such as self-cleaning, anti-icing, drag reduction, and anti-corrosion, it has great application value in the fields of industry, military, and biomedicine. Based on the effect of water contact angle and water sliding angle of superhydrophobic surface on the hydrophobicity, we discussed the wetting behavior of biomimetic superhydrophobic surface, the important properties of biomimetic superhydrophobic surface were reviewed in detail, and we provided the necessary theoretical basis for the application of superhydrophobic surface. The methods of fabrication of biomimetic superhydrophobic surface were summarized and elaborated three kinds of low-cost and simple methods of spraying, chemical etching, and flame treatment, and the development trend of biomimetic superhydrophobic surface was also prospected.

Hydrophobicity and superhydrophobicity with self-cleaning properties are well-known characteristics of several natural surfaces, such as the leaves of the sacred lotus plant (Nelumbo nucifera). To achieve a superhydrophobic state, micro- and nanometer scale topography should be realized on a low surface energy material, or a low surface energy coating should be deposited on top of the micro-nano topography if the material is inherently hydrophilic. Tailoring the surface chemistry and topography to control the wetting properties between extreme wetting states enables a palette of functionalities, such as self-cleaning, antifogging, anti-biofouling etc. A variety of surface topographies have been realized in polymers, ceramics, and metals. Metallic surfaces are particularly important in several engineering applications (e.g., naval, aircrafts, buildings, automobile) and their transformation to superhydrophobic can provide additional functionalities, such as corrosion protection, drag reduction, and anti-icing properties. This review paper focuses on the recent advances on superhydrophobic metals and alloys which can be applicable in real life applications and aims to provide an overview of the most promising methods to achieve sustainable superhydrophobicity.

In this paper, hydrophobic nanocomposite coatings based on polyurethane (PUR) modified by nano-silica and silane-based compounds were manufactured by spraying. The main challenge was to assess and improve the hydrophobic as well as anti-icing properties of initially hydrophilic polymer coatings. The prepared nanocomposite coatings were characterized by means of scanning electron microscopy (SEM), optical profilometry and X-ray photoelectron spectroscopy (XPS). The results obtained showed that in order to achieve hydrophobicity, appropriate amounts of nano-silica must be incorporated in the coating, and complete coverage by nano-silica particles is necessary for achieving hydrophobicity. Coating adhesion and the durability of the hydrophobic behaviour were also studied by scratch test and frosting/defrosting cycles, respectively. The results show that use of both nano-silica and silane-based compounds improve the hydrophobic and anti-icing properties of the coating as compared to a non-modified PUR topcoat. A synergistic effect of both additives was observed. It was also found that the anti-icing behaviour does not necessarily correlate with surface roughness and the materials’ wetting properties.
