In this review, we present an extensive summary of research on superhydrophobic electrodeposits reported in the literature over the past decade. As a synthesis technique, electrodeposition is a simple and scalable process to produce non-wetting metal surfaces. There are three main categories of superhydrophobic surfaces made by electrodeposition: (i) electrodeposits that are inherently non-wetting due to hierarchical roughness generated from the process; (ii) electrodeposits with plated surface roughness that are further modified with low surface energy material; (iii) composite electrodeposits with co-deposited inert and hydrophobic particles. A recently developed strategy to improve the durability during the application of superhydrophobic electrodeposits by controlling the microstructure of the metal matrix and the co-deposition of hydrophobic ceramic particles will also be addressed.

“…It was well known that the multi-scale hierarchical structures play an important role in producing the superhydrophibicity. Also, many strategies have been adopted to construct the dual-scale roughness on the aluminum substrates, mainly including micromachining [27], chemical etching [28], plasma etching [29], electrochemical anodization [30], sol-gel technique [31], and physical coating [32]. Yin et al Among these, the chemical etching route is proved to be one of the most promising approaches, because it is convenient, time-saving, and low-cost.…”

The aim of this paper is to report a facile strategy of planting a layer of petal shaped nanostructures on the surface of array micro-patterns, and producing the excellent superhydrophobicity and anti-icing property. In this work, the superhydrophobic surfaces were prepared by modifying petal shaped nanostructures (constructed by chemical etching in alkaline solution) planted on array micro-patterns (constructed by lithography process with the electrochemical etching under the neutral solution condition) on aluminum substrate with fluoroalkylsilane (FAS-17). Meanwhile, we further studied the effects of chemical etching process parameters on morphology and superhydrophobicity, and on this basis explored the anti-icing potential under the condition of icing wind tunnel. The results indicated that the process parameters including NaOH concentration of 0.05 M, etching time of 5 min, and the subsequent boiling time of 40 min were of benefit to producing the ideal nanostructure morphology and geometric dimension, and the resultant surface displayed an excellent superhydrophobicity with the apparent contact angle of 165° and the sliding angle being almost equal to zero (cannot be measured). Furthermore, the as-superhydrophobic surface generated a tremendous anti-icing potential, greatly preventing the icing accumulation at-10 °C under the condition of icing wind tunnel, and exhibiting a lower ice adhesion strength comparing with a market mature production of superhydrophobic coating.

“…Covalent bonding between the dispersed nanoparticles and composite matrix improves the mechanical stability of the coating, thereby resulting in improved durability. Ammar et al [87] and Zhang et al [88] employed zinc oxide nanoparticles, whereas Liu et al used nickel-based nano electro-brush plating for fabricating a superhydrophobic coating [89]. All methods exhibited variable degrees of mechanical stabilities as well.…”

Engineered superhydrophobic coating for anti-corrosion applications is a subject of great significance at present. However, the use of superhydrophobic coatings for anti-corrosion applications is hindered by the mechanical durability in many cases. There is a need for an understanding not only of how to fabricate such surfaces, but also of the corrosion resistance and mechanical durability of those coatings. This review discusses recent developments in the mechanical durability of superhydrophobic coatings primarily used for anti-corrosion. First, superhydrophobicity is introduced with an emphasis on different wetting models. After that, this review classifies the nanofabrication methods based on the material and methods of surface functionalization. Furthermore, the testing procedures used for the measurement of corrosion and mechanical durability are presented. Finally, the mechanical durability and anti-corrosion performance of the developed superhydrophobic coatings are discussed.
