“…The authors utilized fly ash with a particle size of tens of micrometers to dedust the superamphiphobic CuO film, with contaminants easily removed by 8 μL water droplets. Shu et al 132 employed nanosecond laser processing technology and the sol–gel method to design and fabricate mechanically robust micro- and nanostructures. They developed modified SiO 2 @PDMS superhydrophobic corrosion-resistant coatings on copper substrates.…”

“…36 Sun et al prepared a superhydrophobic surface with a repairable irregular void structure and found that the porous superhydrophobic surface could enhance the stability of the underwater gas−liquid interface and significantly reduce the frictional resistance. 37 39 However, there are obvious drawbacks to generating air cavities for underwater drag reduction using the above method: (1) The micro/nanostructure of SHSs is highly susceptible to damage and poor adhesion between the coating and the substrate, making it difficult for the surface to trap air layers, producing wall slippage and preventing drag reduction under extreme environmental conditions. (2) The Leidenfrost effect generates air cavities that require the spheres to be heated above the Leidenfrost temperature of liquid, but the repeated impingement of spheres into the water causes the surface temperature to drop, causing the vapor layer on the surface to gradually collapse, which in turn affects the hydrodynamic properties.…”

Superhydrophobic surfaces (SHSs) have possibilities for achieving significantly reduced solid–liquid frictional drag in the marine sector due to their excellent water-repelling properties. Although the stability of SHSs plays a key role in drag reduction, little consideration was given to the effect of extreme environments on the ability of SHSs to achieve drag reduction underwater, particularly when subjected to acidic conditions. Here, we propose interconnected microstructures to protect superhydrophobic coatings with the aim of enhancing the stability of SHSs in extreme environments. The stability of armored SHSs (ASHSs) was demonstrated by the contact angle and bounce time of droplets on superhydrophobic surfaces treated by various methods, resulting in an ASHS surface with excellent stability under extreme environmental conditions. Additionally, inspired by microstructures protecting superhydrophobic nanomaterials from frictional wear, the armored superhydrophobic spheres (ASSPs) were designed to explain from theoretical and experimental perspectives why ASSPs can achieve sustainable drag reduction and demonstrate that the ASSPs can achieve drag reduction of over 90.4% at a Reynolds number of 6.25 × 104 by conducting water entry experiments on spheres treated in various solutions. These studies promote a fundamental understanding of what drives the application of SHSs under extreme environmental conditions and provide practical strategies to maximize frictional drag reduction.

The superhydrophobic copper surfaces were fabricated by electrodeposition of copper followed by surface modification with stearic acid (SA). The electrodeposition of copper for 90 s at a voltage of 1.2 V, was identified as the optimum condition via contact angle measurement and used for further investigation. In the next step, the study explored the influence of the solution concentrations and the duration of the modification process. A 0.01 molar SA solution rendered the surface superhydrophobic after 24 h, while 0.1 and 0.25 molar solutions of SA achieved this in 10 min, with the latter exhibiting a larger contact angle(158 ± 2°), and a sliding angle of 3.5°. Fog harvesting experiments demonstrated nucleation, growth, and droplet merging on a superhydrophobic surface. The efficiency of the superhydrophobic surface was calculated to be 4.6 g/cm2. h which is approximately 50% larger than polished surface.
