Due to their superior water-repelling effects, superhydrophobic surfaces have received increasing attention as a promising solution to corrosion of metallic materials. The present article introduces the fundamental theories behind superhydrophobicity followed by a comprehensive review of the recent progresses of this rapidly growing field over the past 5 years. A critical discussion over anticorrosion mechanisms of superhydrophobic surfaces is also provided. For many realistic applications, future efforts are pressingly demanded to prolong the corrosion resistance of these superhydrophobic surfaces. To this end, several important strategies and examples in designing stable, selfhealable, or inhibitor-loaded superhydrophobic surfaces are discussed.

Development of the self-cleaning and anti-fogging superhydrophobic coating for aluminum surfaces which is durable in the aggressive conditions has raised tremendous interest in materials science.In this work, by employing chemical etching technique with mixture of hydrochloric and nitric acid, followed by passivation with lauric acid, superhydrophobic aluminum surface was synthesized. The surface morphology analysis reveals the presence of rough microstructures on coated aluminium surface.Superhydrophobicity with water contact angle of 170 ± 3.9° and sliding angle of 4 ± 0.5° is achieved.Surface bounces off the high speed water jet, indicating excellent water-repellent nature of coating. It is also continuously floated on water surface for several weeks, showing excellent buoyancy nature.Additionally, coating maintains its superhydrophobicity after undergoing 100 cycles of adhesive tape peeling test. Its superhydrophobic nature withstands 90° and 180° bending, and repeated folding and defolding. Coating exhibits the excellent self-cleaning property. In low temperature condensation test, almost no accumulation of water drops on the surface, showing the excellent anti-fogging property of coating. This approach can be applied to any size and shape of aluminium surface and hence has great industrial applications.

“…The anticorrosion performance can nearly result from the air pockets trapped in the knobbly structure. 37,38 Because of the surface tension between water and the hydrophobic hierarchical structures, it was difficult for water to penetrate the superhydrophobic layer when the sample steel was put into 3·5 wt.% sodium chloride solution. Thus, an air protection shield function is found and the corrosive medium is blocked from the superhydrophobic steel surface.…”

A superhydrophobic zirconium film with a hierarchical knobbly structure was prepared by a one-step electrochemical method on the surface of steel. Wettability was determined with a water contact angle of 157°and a sliding angle of 3°. The morphology was characterized with scanning electron microscopy, and the microstructure seemed like it is composed of micro-nano complicated particles. Furthermore, according to the results of Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and energy-dispersive X-ray spectrometry, the chemical composition of the film was zirconium palmitate. Moreover, the chemical and mechanical stabilities of the asprepared superhydrophobic zirconium palmitate surface were characterized by means of electrochemical measurements and abrasion test, respectively. The superhydrophobic surface could yield a stable air-liquid interface by performing as a barrier, from which the diffusion of corrosive media was prevented. On the other hand, the asprepared surface exhibited a good self-cleaning effect, by which the accumulation of contaminants on the surface was not favorable.
