“…In addition to the above preparation methods, other methods were also used to modify PU foams for oil/ water separation, such as electroless deposition 85 and calcination. 86 For instance, Chen et al 86 prepared monolithic ultralight Fe 2 O 3 /C, Co/C, and Ni/C foams by the calcinations of the polyacrylic acid-grafted PU foam at 400 C. The ultra-light foam was composed of three-dimensional (3D) connected hollow tubes with a diameter of micro and nano wall thickness [ Fig.…”

With the development of society, oil pollution has become more and more serious, it is becoming a global issue to separate oil and water mixture. Currently, a variety of functional materials have been successfully prepared for oil/water separation. Among them, polyurethane is an attractive candidate due to its low cost, wear-resistance and excellent mechanical properties. This report summarizes the design strategy of polyurethane-based materials and their applications in oil/ water separation. The progress made so far will guide further development of polyurethane-based materials for oil/water separation.

“…High selectivity has been introduced onto these materials by purposeful construction of befitting surface topography and modification by functional molecules with special wetting property. Different promising routes such as in situ growth, [54] dip coating, [55] polymerized octadecylsiloxane coating, [56] carbon nanotube/ poly(dimethylsiloxane) based coating, [23] block copolymer (BCP) grafting, [57] solution-immersion, [58] sugar templating, [59] vapour phase polymerization [60] for developing special wettability of these materials have been followed by various research groups. Coating of various low surface energy molecule on the surface of sponge based materials are widely used means for attaining superhydrophobiciy and superoleophilicity [23,58,61-63].…”

With the increase of offshore drilling of oil, production and transportation the chances of oil spillage has enormously increased. Oil spillages have a catastrophic impact on our aquatic environment and ecosystem. In the last few years development of special wettable materials for oil-water separation has received tremendous research and industrial interest. Materials with selective wettability, that is superhydrophobic and superoleophilic, or superhydrophilic and superoleophobic, can be used to remove only one phase from the oil/water mixture. Moreover, the effect of the surface chemistry and surface architecture can further promote the superwetting behaviour and improves separation efficiency. In this review, recently developed materials for oil/water separation are summarized and discussed. These materials have been categorized based on their oil/water separating mechanisms that is filtration or absorption. Representative studies are highlighted, with emphasis on the materials wetting properties that is superhydrophobic/superoleophilic or superoleophobic/ superhydrophilic nature, innovative aspects and their applications. The materials with selective wettability can be used for the treatment of oil spills and industrial oily wastewater treatment on an industrial scale. The challenges and future research directions in this emerging and promising research field are briefly described.
