“…[7] In recently, membranes with superhydrophobicity/ superoleophilicity are popular materials for separating emulsified water from oil. [8] While the fabrication of separation membranes always contains intricate processes. Therefore, magnifying the advantages of a superhydrophobic material in both "adsorption" and "separation" for the treatment of oil/ water mixture is worthy of study.…”

COFs were synthesized by a microwave-assisted solvothermal route, with the building blocks containing 1,3,5-tris(4-aminophenyl) benzene and 2,3,5,6-tetra-fluoroterephthalaldehyde (or 1,4-phthalaldehyde). The À F groups introduced into the benzene ring promoted hydrophobicity and stability of the COFs. The universality and long effectiveness of oil adsorption can be realized when applying COFs as adsorbent. The powder also exhibited excellent water-in-oil emulsions separation performance, with the separation efficiency no lower than 99.5%. In this work, the use of microwave solvothermal synthesis of superhydrophobic COFs is potential to replace the conventional synthesis process and more suitable for industrial scale-up production. Furthermore, the findings provide a new strategy for solving the problem of oil spill treatment and industrial water-in-oil emulsions separation by using the emerging 2D COFs.

“…With the rapid development of industrialization, worldwide oil spill and industrial oily wastewater have discharged various toxic compounds to the water systems and thus threaten the global ecosystem [1,2]. Superwetting materials, showing different interfacial effects on oil and water, are effective means for oil/water separation [3][4][5][6][7][8][9][10].…”

“…Wettability is controlled by the chemical composition of the surface and micro/nanoscale surface structures [18][19][20][21]. Inspired by bionics, Jiang et al [22] prepared super hydrophobic and super oleophilic stainless steel mesh film by forming hierarchical micro/nanostructured surfaces through covalent grafting and the self-assembly of hydrophobic groups to successfully and effectively separate oil/water mixture.…”

For continuous and efficient oil/water separation and adsorption of dyes, coconut shell powder was grafted onto the surface of quartz sand by dip-coating method to make coconut shell powder-covered quartz sand filter media (CSQS) with superhydrophilic and underwater superoleophobic properties and superoleophilic and underoil highly hydrophobic properties. The contact angles of the underwater oil and underoil water with CSQS were more than 151.2° and 134.2°, respectively. A continuous oil/water separation device was designed. The separation device filled with CSQS can separate oil/water mixture (whether heavy or light oil) into water and oil at the same time with a separation efficiency of above 99.92%. The filter layer can be recovered through reverse extrusion even after lyophobic liquid penetrated the filter layer; hence, the separation efficiency of the filter layer was still above 99.99% for diesel and water mixture. Simultaneously, CSQS can effectively adsorb methylene blue with the highest removal rate as 98.94%. CSQS can maintain stable wettability under harsh environment conditions. This paper provides a new idea on continuous and efficient oil/water separation and simultaneous dye adsorption.
