Electrophoretic deposition (EPD) is an excellent surface coating approach widely investigated for applications ranging from solar cells, batteries, electrochemical capacitors, solid oxide fuel cells, sensors, molecular sieves, corrosion‐resistant coatings, and biomedical materials. On the other hand, superhydrophobic (SHPC) surfaces have enticed substantial recent research interest owing to their superb surface properties. Here, we provide a comprehensive review of electrophoretic‐deposited SHPC coatings. Concise descriptions of EPD and superhydrophobicity are provided first, followed by a brief mentioning of works reported on electrophoretic‐deposited SHPC coatings by one‐step or two‐step processing (§2.1). The next section (§2.2) delivers a comprehensive description of these reports based on the micro/nanoparticles used. Works reported in specific applications such as anti‐corrosion, biomedical, and oil‐separation are described in §2.3. Future scopes of research also presented.

“…It is higher than the area fraction of air on the M-Al surface, indicating that the micro-nano hierarchical configuration greatly increases the trapped air membrane area at the solidliquid interface. e smaller contact area between solid and liquid also contributes to reducing the adhesion of the MN-Al surface to the brine droplets [38]. Furthermore, the true solid-liquid contact fraction of MN-Al is smaller than that of N-Al surface, indicating that the nano-film structure with multiscale structure is more conducive to reducing the solidliquid contact area and solid-liquid adhesion, so there is a smaller contact angle hysteresis and the brine droplets tend to stay in a stable Cassie state.…”

The problem of oil-water separation regarding oil-containing brine has been of much concern when using the oil pad water dissolution method to construct salt cavern reservoirs. In this paper, oil-water separation materials with micro-nano hierarchical structure were prepared on different metal substrates using chemical etching and electrophoretic deposition. And hydrophobic materials with a single micro/nano structure were also prepared; then, the surfaces were hydrophobized by various low surface energy modifiers. Thereafter, we analyzed and compared the surface morphology, chemical composition, and wettability of all the materials and found that brine contact angles on hierarchical structure surfaces were above 160° while the diesel was completely diffused. Furthermore, preparation parameters affecting the surface morphology and wettability of micro-nano composite structures were explored. Meanwhile, it was found that the surface of prepared composite structure could still maintain super-hydrophobic/lipophilic properties after exposure in air for 6 months, sliding 60 cm on sandpaper, or immersion in diesel/brine for 48 h. Moreover, the composite structure surface displayed improved corrosion resistance with corrected self-corrosion potential and lower corrosion current density. It was equally observed that the studied materials could be better adapted to the actual context of salt cavern reservoir construction and thus have great application prospects.

“…The coating combines the intrinsic hydrophobicity and low surface energy properties of its constituent materials to create an extremely rough micro/nanosurface structure; thus, a filter membrane surface with superhydrophobic and superoleophilic properties is formed on the metal substrates, such as a metal mesh. At present, spray deposition [ 11 , 38 , 39 ], chemical vapour deposition [ 26 ], and electrodeposition [ 40 ] methods are successfully applied in superhydrophobic–superoleophilic filter membranes fabrication.…”

In recent years, oil–water separation has been widely researched to reduce the influences of industrial wastewater and offshore oil spills. A filter membrane with special wettability can achieve the separation because of its opposite wettability for water phase and oil phase. In the field of filter membrane with special wettability, porous metal filter membranes have been much investigated because of the associated high efficiency, portability, high plasticity, high thermal stability, and low cost. This article provides an overview of the research progress of the porous metal filter membrane fabrication and discusses the future developments in this field.
