“…There are other examples where this combination of properties has been used to engineer materials for oil/water separation (Zhu et al, 2017 ; Ge et al, 2019 , 2020a ). A variety of nanomaterials have been used to create meshes (Jiang et al, 2017 ; Zhang et al, 2018a , 2019 ; Nanda et al, 2019 ; Wang et al, 2019 ; Gong et al, 2020 ), membranes (Attia et al, 2018 ; Huang et al, 2018 ; Ma et al, 2018 ; Qing et al, 2018 ; Zhao et al, 2018 ; Subramanian et al, 2019 ; Cheng et al, 2020 ), sponges (Huang et al, 2019b ; Li et al, 2019b ), and fabrics (Cheng et al, 2018 ; Chauhan et al, 2019 ; Lin et al, 2019 ; Zhou et al, 2019 ; Dan et al, 2020 ) with superhydrophobic and superoleophilic properties for oil/water separation (Ferrero et al, 2019 ; Zulfiqar et al, 2019 ; Latthe et al, 2020 ; Lin et al, 2020 ; Topuz et al, 2020 ; Zhang et al, 2020b ). Most of these materials separate oil either by filtration, absorption, or both.…”

Oil/water mixtures are a potentially major source of environmental pollution if efficient separation technology is not employed during processing. A large volume of oil/water mixtures is produced via many manufacturing operations in food, petrochemical, mining, and metal industries and can be exposed to water sources on a regular basis. To date, several techniques are used in practice to deal with industrial oil/water mixtures and oil spills such as in situ burning of oil, bioremediation, and solidifiers, which change the physical shape of oil as a result of chemical interaction. Physical separation of oil/water mixtures is in industrial practice; however, the existing technologies to do so often require either dissipation of large amounts of energy (such as in cyclones and hydrocyclones) or large residence times or inventories of fluids (such as in decanters). Recently, materials with selective wettability have gained attention for application in separation of oil/water mixtures and surfactant stabilized emulsions. For example, a superhydrophobic material is selectively wettable toward oil while having a poor affinity for the aqueous phase; therefore, a superhydrophobic porous material can easily adsorb the oil while completely rejecting the water from an oil/water mixture, thus physically separating the two components. The ease of separation, low cost, and low-energy requirements are some of the other advantages offered by these materials over existing practices of oil/water separation. The present review aims to focus on the surface engineering aspects to achieve selectively wettability in materials and its their relationship with the separation of oil/water mixtures with particular focus on emulsions, on factors contributing to their stability, and on how wettability can be helpful in their separation. Finally, the challenges in application of superwettable materials will be highlighted, and potential solutions to improve the application of these materials will be put forward.

Inspired by the lotus leaves in nature against contaminants in the muddy environment, superhydrophobic phenomena has attracted tremendous attentions among the research communities, and triggered the researchers to fabricate an artificial superhydrophobic surface for real-time applications. In this paper, the development of bioinspired materials is combed in accordance with time evolution. Besides, the advantages/disadvantages of numerous preparations in superhydrophobic coating are discussed through the recent researches. In addition, the recent advances of superhydrophobic applications are summarized, such as self-cleaning behavior, anti-icing properties, anti-corrosion performance and oil/water separation. Particularly, this review introduces the mechanism and implementation of anti-icing properties by superhydrophobic coating. As for superhydrophobic coating, current challenges are pointed out and its future development for applications is prospected. Overall, this review provides a reference for research and development of superhydrophobic coatings.

“…Self-cleaning surfaces may be split into two parts, hydrophilic surfaces and hydrophobic surfaces. Due to its water-repellent properties and low adhesive surface, the water droplets roll on the surface easily in the case of hydrophobic surfaces and in turn eliminates contaminants [19][20][21].…”
