“…Through extensive investigation on the natural and artificially prepared superhydrophobic surfaces, it has been confirmed that the key factors to cause the superhydrophobicity are chemical compositions that decide the surface free energy and the geometric structure at microscopic level that controls the surface roughness [72][73][74][75][76]. On a perfectly flat surface, the CA of a water droplet can only reach up to around 120° by reducing the surface free energy (the lowest surface free energy was reported to be around 6.7 mJ m -2 , which was attained by regularly aligned closest-hexagonal-packed -CF 3 groups) [77,78].…”

“…Thus, Wenzel's approach is called homogeneous wetting. According to the literature [37][38][39], the adhesion force was pointed out proportional to the van der Waals forces and the negative pressures produced by the air sealed in the surface. When the droplet was placed on the superhydrophobic surface, the negative pressures can be neglected.…”

Superhydrophobicity is one of the most required surface properties for a wide range of application such as self-cleaning, anti-corrosion, oil-water separation, anti-icing, and anti-bioadhesion. Recently, several methods have been developed to produce nature inspired super-hydrophobic surfaces. Nevertheless, these methods require a complicated process and expensive equipment. In order to overcome these issues, we propose three different methods to obtain nature-inspired super-hydrophobic surfaces: short-term treatment with boiling water, HF/HCl and HNO3/HCl concentrated solution etching. Afterwards, a thin layer of octadecylsilane was applied by in situ polymerization on all pre-treated surfaces. Eventually, all substrates were dried for 3 h at 100 °C to complete the silane curing. Scanning electron microscopy (SEM), contact angle measuring system and atomic force microscope (AFM) were used to characterize the surfaces. Surface morphology analysis showed that each method results in a specific dual hierarchical nano-/micro-structure. The corresponding water contact angles ranged from 160° to nearly 180°. The best results were observed for HF etched Al 6082 surface were water contact angle above 175° was achieved. Furthermore, a scheme able to assess the relationship between hydrophobic behavior and surface morphology was finally proposed.

“…31 Zn-Ni electrodeposits, etched with NaOH to change the surface roughness and then coated with myristic acid, repel water droplets that have volumes of 10s of μL. 21 Water droplets with μL volumes also slide easily off anodically produced CuO needles with fluoroalkyl-silane surface modification. 32 This suggests that many different kinds of surface topographies and chemistries can be effective for water-repellency, and that electrodeposition can play a useful role.…”

“…Electrodeposits change the surface topography, and some studies have checked to see if this correlates with changes in static contact angles. [20][21][22] Adding surfactants to electrolytes is another strategy to control crystallite nucleation and growth. Such additives can alter the evolution and adsorption of hydrogen gas, and they can also passivate specific crystallite faces to alter crystallite morphologies.…”

We show that mildly alkaline electrolytes can be used to produce Zn coatings that improve the water repellent properties of stainless steel. Optimal Zn deposits were prepared under potentiostatic conditions from electrolytes that contained ZnCl 2 , NH 4 Cl, and a surfactant (polyethyleneimine). After deposition, the Zn electrodeposit was capped with stearic acid to prevent oxidation and to provide a lower surface energy. The capped electrodeposits display an impressive degree of water repellency, including extremely poor water droplet adhesion. We discuss the range of deposition parameters (electrolyte composition, pH, and applied potential) that produce the best water-repellent electrodeposits.
