“…The decrease of the corrosion current density of about two orders of magnitude is a result comparable to literature data evidencing corrosion protecting performances of SH coatings [15,27,28]. It is known that the corrosion protection afforded by SH coatings depends on the combined action of the coating itself and the air plastron entrapped within the texture of the SH coating surface [29][30][31]. Some authors went inside this concern, evidencing the important role of trapped air as a dielectric inhibiting electron transfer between the electrolyte and the substrate [32].…”

Superhydrophobic Coatings from Recyclable Materials for Protection in a Real Sea Environment

Recyclable materials can be referred to as both those materials directly recycled from wastes and those derived from any kind of transformation before use. Highly water repellent coatings with wettability properties, known as superhydrophobic (SH), are related to surfaces with contact angles above 150° and a very small hysteresis. The small area available for these surfaces when in contact with water can be exploited in many applications in which interactions with an aqueous environment are usually desirable to be avoided, like for protection and friction reduction in a marine environment. SH coatings under investigation have been prepared starting from recyclable materials with the aim to provide a sustainable and low cost solution, with potential application to large surfaces in a marine environment. Wetting studies, surface characterization, and electrochemical tests show how these surfaces can be used in terms of fouling prevention and the protection of metals in underwater conditions.

“…The morphology of products can be precisely controlled by regulating the reaction temperature, reaction time, or the concentration of chemicals. Wan et al developed a superhydrophobic copper surface for corrosion protection via the hydrothermal method [50]. The copper was etched in ammonia solution for 20 h and then placed in an autoclave containing 60 mL of NaOH solution (0.2 mol/L) to react for 2 h at 200 • C. The surface showed a WCA of 157.7 ± 1 • after modification by stearic acid.…”

Superhydrophobic surfaces have drawn attention from scientists and engineers because of their extreme water repellency. More interestingly, these surfaces have also demonstrated an infinite influence on civil engineering materials. In this feature article, the history of wettability theory is described firstly. The approaches to construct hierarchical micro/nanostructures such as chemical vapor deposition (CVD), electrochemical, etching, and flame synthesis methods are introduced. Then, the advantages and limitations of each method are discussed. Furthermore, the recent progress of superhydrophobicity applied on civil engineering materials and its applications are summarized. Finally, the obstacles and prospects of superhydrophobic civil engineering materials are stated and expected. This review should be of interest to scientists and civil engineers who are interested in superhydrophobic surfaces and novel civil engineering materials.
