“…In other words, these materials are actually hydro-responsive. [30][31][32][33] As a typical example, Yang et al reported a superhydrophilic and superoleophobic coating material that can be applied on various substrates, e.g., metals, glasses, etc. [ 32 ] This special composite consisted of hydrophilic poly(diallyldimethylammonium chloride) (PDDA), oleophobic sodium perfl uorooctanoate (PFO) and SiO 2 nanoparticles, referred to as PDDA-PFO/SiO 2 .…”

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.

“…When these materials are in contact with water, their hydrophilic components move to surface, and the hydrophilicity and oleophobicity are obtained. [17][18][19][20] Inspired by sh scales, 21 another innovative approach to achieve the "water-removing" materials, that is, developing superhydrophilic and underwater superoleophobic materials is proposed recently by researchers. Based on Young's equation, hydrophilic surfaces in air can become oleophobic in water, 22 and underwater superoleophobic surfaces could be obtained by design of hydrophilic chemical compositions and micro/nano hierarchical structures.…”

“…The obtained separation efficiency greater of over 97% at a 789 L m −2 hr −1 flux after 20 separation cycles indicates that the present PSMA/MWNTs/FS membrane filter exhibits excellent recyclability and could be employed for practical oil/water separation. The performance of the oil/water separation membrane filter developed in this study is summarized in Table S5, compared with the reference data of some water stimulus‐response oleophobic/hydrophilic surface reported previously …”

Polymer/fluorocarbon surfactant membranes have been reported to display excellent oleophobic/hydrophilic behavior and outstanding oil/water separation properties. In this work, multiwalled carbon nanotubes (MWNTs) enhanced poly(styrene‐alt‐maleic anhydride)/fluorocarbon surfactant (PSMA/MWNTs/FS) membrane filters were prepared by dip‐coating PSMA/MWNTs/FS on stainless steel meshes for efficient oil/water separation. The microstructure, thermal properties, wettability, oil/water separation ability, and recyclability were investigated. The results revealed that the MWNTs are suitably dispersed in the membrane, further increasing the thermal stability, oil/water separation efficiency, and recyclability. The oil/water separation efficiency of the complex membrane filter containing MWNTs was 99% initially and 97% after 20 cycles. This work provides a simple, low‐cost, and environmentally friendly approach for efficient oil/water separation.
