“…Among the different oil/water removal approaches, the oil removing method is preferable as oil is typically the minor component. The material (oil removing filters or oil absorbents) should be SHPC and underwater superoleophilic (SOPL) to remove oil from water [49,66,108,138] …”

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.

“…To build the mechanically durable rough surfaces required for the robust superwettable membranes, many other unique approaches, in addition to the cross‐linked coating strategy, have emerged. For example, abrasion‐tolerant oil–water separation systems can be prepared by electrodeposition, layer‐by‐layer assembly, chemical etching, femto/nanosecond laser, O 2 plasma attack, and electrospinning …”

Over the past decade, much progress has been made in the application of multifunctional membranes with special wettability for the separation of oil–water mixtures. This progress has been driven by frequent oil spill accidents and oily wastewater, which are enormous threats to the vulnerable aquatic environment. The design of permeable superwettable membranes for oil–water separation has been inspired by the development of highly wetting/nonwetting interfaces, but these membranes are susceptible to factors such as mechanical forces, chemical corrosion, biological fouling, and other environmental influences. Considering the complex and harsh environments that superwettable membranes must endure during the separation process, membrane durability against the loss of superwettability is critical in prolonging the life of an oil–water filtration system. Although significant advances in superwettable membranes have been made, the robustness issue remains challenging and has become a focus of many investigations. Covering nearly all publications concerning “robust, durable, usable, resistant, tolerant, or antifouling oil–water separation” published in the last five years, this work is intended as an introduction for new researchers wishing to create durable superwettable membranes for oil–water separation, as well as providing perspectives and guidance for future research in several logical directions.

“…2,3 To date, superhydrophobic and superoleophilic materials with the substrates of metallic meshes and fabrics have been successfully developed and achieved reasonable success in separating oil/water immiscible mixtures. [4][5][6][7][8][9][10][11][12] Such superhydrophobic and superoleophilic surfaces allow oil to permeate easily, while rejecting water droplets in the oil-liquid emulsion by controlling the pore structure or their own surface properties. Thus, water droplets can be effectively separated from the oil-liquid emulsion.…”

Superhydrophobic and superoleophilic glass-fiber fabric with high water-in-oil emulsion separation efficiency was prepared by a simple sol-gel process using MTES (triethoxymethylsilane) as precursor. The surface chemical composition, micromorphology, pore size distribution, thermal stability, and the wetting behavior of the glass-fiber fabric were characterized using scanning electron microscopy, Fourier transform infrared spectroscopy, capillary flow porometry, thermogravimetric analysis, and water (pH ¼ 1-14)/oil contact angle measurement. The contact angle of the treated fabric at different temperatures was tested in a muffle furnace. The results show that the micromorphology of the glass-fiber fabric almost remains the same after MTES treatment, while the pore size of the treated glass-fiber fabric decreases slightly. Hydrophobic -CH 3 groups are grafted onto the fiber surface and MTES copolymers are formed on the junction of fibers of the glass-fiber fabric. The treated glass-fiber fabric shows superhydrophobicity and superoleophilicity and its separation efficiency for emulsified water in the oil can reach 96.80 wt %. Besides, the treated glass-fiber fabric can withstand acid/alkaline, high temperature environments and maintain high separation efficiency after multiple cycle uses.
