“…In a study by Rius-Ayra and team, a superhydrophobic CuFeCo alloy powder was synthesized by combining liquid phase deposition and the high-energy ball milling synthesis method to remove high-density polyethylene fibers from water. 72 This study reveals the potential of this method for the synthesis of NMs that can be applied for the removal of MPs from wastewater. Additionally, the main advantage of this method is that it is useful for large scale production of nanoparticles with a high purity and superior physical properties in a cost-friendly manner.…”

Microplastics (MPs) and nanoplastics (NPs) infiltrate aquatic environments at an alarming rate, posing a serious threat to aquatic ecosystems and human health. Wastewater treatment plants are significant sources of MPs/NPs contamination in the aquatic environment, since they are inadequate at removing these MPs/NPs. This calls for the development and application of new technologies for MPs/NPs removal. Recent studies have demonstrated that nanomaterials (NMs) are effective in the removal of MPs from wastewater. This review examines MPs/NPs removal from wastewater using NMs. Despite a specific synthesis of NMs adapted for MP removal from water bodies not being clearly defined, the review assesses the current state of knowledge in relation to MPs/NPs removal from wastewater using NMs and the effect of water characteristics on the removal mechanism. Additionally, various insights into NM development based on specific interactions are addressed and linked to their suitability for wastewater treatment. There is currently considerable interest in chemically synthesizing NMs for the removal of MPs from wastewater. However, further developments are needed in the areas of physical and green synthesis of NMs for the removal of MPs. This review provides a baseline for future research and development of NMs for removing MPs from wastewater.

“…Cheng [13] used the ultrasonic assisted in-situ growth method to deposit composite nanoparticles formed by cashew phenol and ethyl orthosilicate on a cotton fabric surface to prepare superhydrophobic cotton fabric with excellent oil-water separation efficiency, but its raw material cashew phenol is very expensive. Rius-Ayra et al [14] prepared ferromagnetic CuFeCo powder combined with high-energy ball milling and liquid-phase deposition. The powder was functionalized with dodecanoic acid, which not only can remove microplastics but also has superhydrophobic properties.…”

Caffeic acid (CA) was treated on the surface of polyester fabric (PET), and Fe2+ was used as an intermediate to form chelates with CA to increase the roughness of the polyester surface. With the addition of n-octadecyl mercaptan (SH), the mercapto group reacted with the carbon–carbon double bond of CA on the PET surface through enol click chemical reaction. Meanwhile, CA was polymerized under UV radiation, and thus CA-Fe-SH-PET was prepared. The introduction of SH with a long carbon chain reduced the surface energy of the PET, in order to endow the polyester fabric with a superhydrophobic/lipophilic function. Combined with XPS and FTIR tests, the new carbon–carbon double bond’s binding energy and vibration peak were found on the fabric surface, indicating that CA was adsorbed on the PET fabric’s surface. After adding SH, the double bond disappeared, demonstrating that SH and CA occurred a click chemical reaction and were grafted onto the PET fabric’s surface. The water contact angle (WCA) of CA-Fe-SH-PET was about 156 ± 0.6°, and the scrolling angle (SA) was about 3.298°. The results showed that the modified polyester had a robust superhydrophobic stability in washing, mechanical friction, sun aging, seawater immersion, organic reagent, and acid-base erosion derived from the good adhesion of polymerized CA (PCA). At the same time, the modified polyester fabric had good self-cleaning, antifouling, and oil–water separation performance. It was found that the CA-Fe-SH-PET fabric had unique photothermal conversion characteristics, which can convert the absorbed ultraviolet light into thermal energy, providing a local warming effect due to rapid heating and improving the transmission speed of heavy oil (engine oil and diesel). The CA-Fe-SH-PET fabric can further prevent the transmission of ultraviolet rays, and the UV resistance of CA-Fe-SH-PET fabric is far higher than the UV resistance standard. The preparation method is simple, fast, efficient, and environmentally friendly, and it has better a potential application value in the oil–water separation field.
