“…After abrasion for a given time interval, the specimen was removed from the tray, washed in ultrasonically de-ionized water for 3 min and dried with filter paper subsequently air drying for 30 min. After air dried the WCA and roll-off angles were measured and compared the subsequent changes [166][167][168].…”

Increasing interests have been prevalent lately among the research fraternity for the development of superhydrophobic surfaces considering the favorable properties exuded by them. Recently, anti-microbial superhydrophobic coatings have been employed effectively in anti-biofouling, corrosion resistance, and self-cleaning, anti-reflecting coating, biomedical and cavitation erosion applications. Further, patterned topology by micro/nano surface texturing has been perceived as an engineering opportunity to enhance the surface performance and has opened various avenues for exploration. This work reports the recent research findings pertaining to the concept of superhydrophobicity and micro-texturing particularly in the context of their application for the impediment of corrosion in submerged components. The comprehensive review on superhydrophobic surfaces and micro-texturing suggests that the integrated application of these surface modification techniques for mechanical interlocking of deposited coating.

“…33 Metal surfaces like aluminum, copper, and stainless steel are coated with superhydrophobic materials to prevent icing. [32][33][34][35] In this regard, semiconductor materials such as tin oxide have been widely considered coating metal surfaces as they have high band gaps, robust structural strength, and good optical properties, making them an ideal choice for coating metal surfaces. These materials are used in gas sensors, solar cells, and energy storage applications.…”

In the current work, the chemical etching process and hydrothermal method were used to create bio‐inspired superhydrophobic fluorine‐free tin oxide nanostructures on copper plates. Taguchi's experimental design was also used in investigating coating wettability characteristics based on fabrication parameters. Statistical analysis results demonstrated that the optimal superhydrophobic sample with a water contact angle of 163.40° ± 1.42° and contact angle hysteresis of 3.00° ± 0.80° could be fabricated under the following conditions: sodium hydroxide (2.00 M) as an etching solution, urea‐to‐tin chloride ratio 2.5:1, and 2.00 h reaction times. The effects of each synthesis parameter on the obtained sample's superhydrophobicity were evaluated through multiple one‐variable‐at‐a‐time experiments. Testing the chemical stability of the optimal sample revealed that it was more resistant to deterioration in an alkaline environment (8–10) than in an acidic environment (4–6). The resulting superhydrophobic sample was analyzed by a delay test for water droplets freezing on its surface to determine whether ice formed and accumulated. The created bio‐inspired honeycomb‐like nanocoating demonstrated exceptional mechanical robustness and good anti‐icing performance after 10 consecutive icing cycles. These results indicated that superhydrophobic coatings could be easily and economically produced without using fluoropolymers and silanes on aluminum substrates.
