“…Compared with commercial monolithic PU or MS, polystyrene (PS) foam is another common porous monolithic polymer material used in the field of oil spill removal. Importantly, the PS material has inherent hydrophobicity and thus can be used for oil/water separation directly. , The high-internal-phase emulsions (HIPEs) method is often adopted to fabricate the porous and low-density monolithic PS foam material, which is made up of an excess of 74% internal phase dispersed within a continuous external phase . Porous polymer skeleton polyHIPEs were obtained after polymerization of the continuous phase and removal of the dispersed phase .…”

Frequent oil spill accidents and leakage of organic solvent destroy aquatic ecosystems and threaten marine lives. Separation of the oily pollutant from water with material has long been treated as an effective and environmentally friendly solution. As a result, great efforts have been made to construct a material with high oil adsorption capacity, high oil−water separation efficiency, high oil−water selectivity, and superior recyclability. Surface chemical composition and surface topography are two key factors that determine the surface wettability and oil−water separation efficiency of a material. In this review, we summarize the popular oil−water separation materials during the past five years, including adsorption material, filtration material, and smart controllable special wettable separation material. Before that, a basic theory of surface specific wettability is introduced. The perspectives and challenges of each material are also highlighted.

“…Taking the intrinsic hydrophobic performance of PSDVB, the final foam exhibited superhydrophobic-superoleophilic surface for oil-water separation. [45] Moreover, given the magnetic driven capacity of Fe foam, the final Fe@PSDVB foam exhibited oil-removal ability in confined space under remote magnetic driven. Figure 1a,b displays the typical scanning electron microscopy (SEM) images of the Fe foam before and after the free radical polymerization, respectively.…”

Magnetic and superhydrophobic materials with robust physical/chemical stability for controllable and remote magnetic driven capacity for oil removal under harsh environments are meaningful for oil–water separation but still a challenge. Herein, an alternative strategy to address this challenge is demonstrated by decorating poly(styrene‐co‐divinylbenzene) (PSDVB) on Fe foam via one‐pot solvothermal method. Different from previous magnetic and superhydrophobic materials, Fe foam is chosen to replace Fe3O4 nanomaterials. Thus, complicated preparation procedures and the high cost for Fe3O4 nanomaterials can be avoided. Additionally, PSDVB coating provides the whole foam with robust physical/chemical stabilities: i) the surface wettability can be maintained after 50 abrasion cycles or exposed in humid air (relative humidity: 90%) for 14 days, and ii) the surface wettability does not change under different pH solutions (3 < pH < 12) or highly salty solution (NaCl 10 wt%) for 6 h. Besides, outstanding separation efficiency (>99.9%), high durability (>70 times), and excellent oil flux (16 963–75 156 L m−2 h−1) can be realized under gravity. Most importantly, the foam continuously removes oil from confine place (on water surface or under water) under magnetic driven force.

“…One unique characteristic of membranes prepared from such materials is the ability to control their pore size in order to separate specific materials more efficiently. Furthermore, it has been reported that highly porous polymeric materials can be employed for oil‐spill remediation 5 . For example, we can consider porous poly( t ‐butylmethacrylate‐co‐divinylbenzene) modified with silane, whose rate of kerosene adsorption is extremely high, or highly porous polystyrene, which can rapidly adsorb oil 6‐9 .…”

In this study, hydraulic treatment was performed to fabricate porous cellulose acetate (CA) membranes for application as adsorbents for impurities. For this purpose, porous CA membranes were prepared by applying a water pressure of 8 bar on CA dissolved in a mixed solvent of acetone and water. These porous polymers could separate impurities from 2‐n‐octyl‐4‐isothiazolin‐3‐one (OIT) by providing adsorption surfaces for the suspended impurities and allowed pure OIT to filter through the membrane; the filtered OIT may subsequently be used for octyl‐group quantification. After impurity adsorption, the degree of OIT permeation in the CA membrane and the adsorption mechanism of CA were investigated by Fourier transform infrared spectroscopy and water‐adsorption studies. Further, we analyzed the porous characteristics and behavior of CA by scanning electron microscopy and conducted thermogravimetric analysis to observe the physical and chemical changes occurring in the polymers.
