Oil sorbents play a significant role in the treatment processes of oil spills, therefore, enhancing the oil-water separation capacity of sorbents has been charming the consideration of scientific researchers. To improve the properties of oil sorption and simplify the process of oil recovery, many advanced oil sorbent devices have been projected recently. Different types of materials are used as sorbents for oil-water separation, however, up to now, there is no review paper focused on textile (woven, knitting, and nonwoven) sorbents, and compared with them. In this review paper, the classification of textile fabrics, properties of surface wetting, fabrication methods of textile sorbents for oil spill cleanup, their properties, and recent applications in the field of oil cleanup are studied. We believe this review can serve as an essential reference for the formation of textile sorbents, their properties, and their applications in the field of oil spill cleanup.

“…With the development of science and technology, environmental protection has been attracting extensive interest. Oil and water mixtures generated from oil spills and long-term industrial production significantly affect the environmental balance, endangering marine organisms and economic development [ 1 , 2 , 3 , 4 , 5 ]. Therefore, repairing the vulnerable ecosystem is critical [ 6 , 7 ].…”

Oil/water mixtures from industrial and domestic wastewater adversely affect the environment and human beings. In this context, the development of a facile and improved separation method is crucial. Herein, dopamine was used as a bioadhesive to bind tea polyphenol (TP) onto the surface of a polyvinylidene fluoride (PVDF) membrane to form the first hydrophilic polymer network. Sodium periodate (NaIO4) is considered an oxidising agent for triggering self-polymerisation and can be used to introduce hydrophilic groups via surface manipulation to form the second hydrophilic network. In contrast to the individual polydopamine (PDA) and TP/NaIO4 composite coatings for a hydrophobic PVDF microfiltration membrane, a combination of PDA, TP, and NaIO4 has achieved the most facile treatment process for transforming the hydrophobic membrane into the hydrophilic state. The hierarchical superhydrophilic network structure with a simultaneous underwater superoleophobic membrane exhibited excellent performance in separating various oil-in-water emulsions, with a high water flux (1530 L.m−2 h−1.bar) and improved rejection (98%). The water contact angle of the modified membrane was 0° in 1 s. Moreover, the steady polyphenol coating was applied onto the surface, which endowed the membrane with an adequate antifouling and recovery capability and a robust durability against immersion in an acid, alkali, or salt solution. This facile scale-up method depends on in situ plant-inspired chemistry and has remarkable potential for practical applications.

“…In contrast, some studies only focused on the property of SHL&UWSOB for light oil/water separation, but further superhydrophobic modification was usually needed for heavy oil/water separation using SHB&SOL membrane. 31,32 Herein, a superhydrophilic hybrid layer on the NF surface was constructed by the initial affinity of dopamine (DA), followed by in situ growth of metal-organic framework (MOF) via solvothermal synthesis. Triethylamine was used to accelerate the deprotonation of the organic ligands in the form of Fe/ Ni MOF on the NF surface.…”
