“…The commercial meshes (knitted by smooth wires according to square arrangement) with various pore sizes are an excellent substrate to fabricate functional film with special wettability to achieve the efficient oil-water separation [15][16][17][18][19][20][21][22][23][24]. Two stainless steel meshes with pore sizes of ca.…”

“…ZnO micro-or nanostructures, especially nanowire, nanorod and nanoflower, were often created on varied substrates (such as silicon, glass, mesh and fiber) to obtain superhydrophobic and ultraviolet (UV)-responsive wettable surfaces due to the properties mentioned above [14][15][16][17][18][19][20]. A few synthetic strategies, such as sputter deposition, electrochemical deposition, hydrothermal route, and chemical vapor deposition (CVD) have been employed to fabricate kinds of ZnO micro-or nanostructures [14][15][16][17][18][19][20]. Among them, CVD is a promising route because of its high controllability in terms of the crystal structure, geometry, and growth rate [14].…”

“…Recently, in order to promote uniform and well-controlled surface roughness on metallic mesh substrates, the in situ growth of metal oxide crystals on mesh substrates through a controllable chemical reaction were reported. [21][22][23] For example, Wang et al prepared a ZnO-coated stainless steel mesh via the hydrothermal reaction. By varying the reaction time, the morphology of the ZnO coating could be well-controlled, and the WCA and OCA of the obtained ZnO-coated stainless steel mesh can reach 160° and 0°, respectively.…”

The increasing number of oil spill accidents have a catastrophic impact on our aquatic environment. Recently, special wettable materials used for the oil/water separation have received significant research attention. Due to their opposing affinities towards water and oil, i.e., hydrophobic and oleophilic, or hydrophilic and oleophobic, such materials can be used to remove only one phase from the oil/water mixture, and simultaneously repel the other phase, thus achieving selective oil/water separation. Moreover, the synergistic effect between the surface chemistry and surface architecture can further promote the superwetting behavior, resulting in the improved separation efficiency. Here, recently developed materials with special wettability for selective oil/water separation are summarized and discussed. These materials can be categorized based on their oil/water separating mechanisms, i.e., filtration and absorption. In each section, representative studies will be highlighted, with emphasis on the materials wetting properties and innovative aspects. Finally, challenges and future research directions in this emerging and promising research field will be briefly described.

Superhydrophobicity is an interesting surface property underlying several fascinating natural phenomena, such as the self-cleaning ability of lotus leaves and the striding ability of spiders, which have attracted much interest in the industry and academia. A superhydrophobic surface is that on which the water contact angle (WCA) is higher than 150 o and the water sliding angle is lower than 10 o , hence, water droplets can easily slide/run off the surface. This principle of high water repellence of a superhydrophobic surface can be extended to practical applications, for example, to develop coatings for automobile windows, tiles, buildings, and clothes.
