A new class of superhydrophobic surface based on multiple hybrid coatings is proposed and prepared to improve mechanical and reproduction stability. It does not only show a large water contact angle (ca. 174.5°) but also a slight decrease (ca. 6.4%) of water contact angle after 100 mechanical abrasion cycles. Furthermore, the water contact angle changes slightly (relative standard deviation, 0.14%) for the three superhydrophobic surfaces prepared with the same procedure. The application of superhydrophobic multiple hybrid coatings in corrosion protection is further investigated by the Tafel polarization curves and electrochemical impedance spectroscopy. The superhydrophobic multiple hybrid coatings showed lower corrosion current (1.4 × 10–11 A/cm2), lower corrosion rate (ca. 1.6 × 10–7 mm/year), and larger polarization resistance (7.9 × 104 MΩ cm2) in 3.5 wt % NaCl aqueous solution compared to other superhydrophobic coatings reported in previous works. This work not only confirms the formation of robust superhydrophobic surface for real application in corrosion protection but also provides a new model of superhydrophobic surface based on multiple hybrid coatings with high mechanical, chemical, and reproduction stability for various applications.

“…The contact angle of pure Cu foil is approximately 85.2°, whereas the contact angle of the Cu–MoS 2 current collector surface is increased to 135.7° because of the presence of the micro/nanostructure, exhibiting poor wettability. In general, the poorer the wettability of the film, the better the corrosion resistance is, because the film can effectively reduce the contact between the corrosive medium and substrate . Thus, the corrosion medium cannot penetrate into the film .…”

The interface between the current collector and active material is the primary interface of charge transfer. Herein, we designed an effective strategy to optimize the interface architecture by depositing molybdenum disulfide on the copper foil surface (Cu−MoS 2 ) via magnetron sputtering. The Cu−MoS 2 is directly used as a current collector and supports the Li 4 Ti 5 O 12 anode (Cu−MoS 2 −LTO). Typically, after being cycled at 1 A g −1 for 300 cycles, the capacities of the Cu−LTO cell and Cu−MoS 2 cell are about 114.94 and 128.35 mA h g −1 , respectively, whereas the capacity of the Cu−MoS 2 −LTO cell is as high as 373.9 mA h g −1 with a capacity retention rate of 89.1%. The MoS 2 not only optimizes the interfacial architecture but also provides an additional capacity contribution to the Cu−MoS 2 −LTO cell. Based on scanning electron microscopy and X-ray photoelectron spectroscopy test analysis, we propose a dual interface model. It is revealed that the molybdenum disulfide film can significantly improve the charge-transfer efficiency and uniformity of the interface, reduce internal resistance of the batteries, prevent oxidation of the copper foil, and thereby improve the chemical stability of the current collector. In addition, magnetron sputtering technology has large-scale productivity and greatly enhances the industrial application of this strategy.

In recent years, superhydrophobic media has attracted tremendous attention due to its industrial applicability value, especially in anti-corrosion performance. The superhydrophobic coating, which has a robust and water-repellent capacity, can catch the air to form several "airbags" on the substrate's surface, isolating the corrosion media. Various superhydrophobic coating preparation technologies have been suggested, but each has its own set of flaws. On the other hand, electrodeposition, as a relatively mature industrial processing application, offers distinct advantages. However, until now, there have been few reviews on the electrodeposition preparation of anticorrosive superhydrophobic coatings. Therefore, the author has described several fabrication techniques based on superhydrophobic coatings in this review, including the advantages and disadvantages. Superhydrophobic coatings conventional concepts and wettability, as well as the model wetting concepts, have been reviewed. The coating processing status and the corrosion-resistant potential through the electrodeposition of metal and comparable composite are detailly encapsulated. Furthermore, electrodeposition parameters, including current density, crystal modifiers, and a deposition time of the coating morphology, are reported, following the ultrasonic-assisted, jet, pulse, and magnetic field-induced electrodeposition, respectively, as the recently developed technologies for preparing a coating. Finally, technology limitation is shown as well as the obstacles and prospects, and the improvement of the superhydrophobic coating's durability as a prospects research focus has been recommended.
