“…However, the applications of hydrophobic surfaces are still hampered by lengthy preparation procedures and high-cost manufacture. Recently, there have been many reports of fabricated non-fluorinated superhydrophobic fabrics with both oil/water separation properties and with antibacterial areas [ 199 ], flame-retardant finishing [ 200 ], UV shielding [ 201 ], self-cleaning [ 201 , 202 ], intelligent self-healing [ 203 ] or photocatalytic properties [ 204 ] of cellulosic cotton fabric surfaces. a durable superhydrophobic and antibacterial cotton fabric that demonstrated high oil/water separation capacity for a broad variety of oils and organic solvents.…”

Recent developments in the application of lignocellulosic materials for oil spill removal are discussed in this review article. The types of lignocellulosic substrate material and their different chemical and physical modification strategies and basic preparation techniques are presented. The morphological features and the related separation mechanisms of the materials are summarized. The material types were classified into 3D-materials such as hydrophobic and oleophobic sponges and aerogels, or 2D-materials such as membranes, fabrics, films, and meshes. It was found that, particularly for 3D-materials, there is a clear correlation between the material properties, mainly porosity and density, and their absorption performance. Furthermore, it was shown that nanocellulosic precursors are not exclusively suitable to achieve competitive porosity and therefore absorption performance, but also bulk cellulose materials. This finding could lead to developments in cost- and energy-efficient production processes of future lignocellulosic oil spillage removal materials.

“…At this stage, these surface change had become unfavorable toward the formation trapped air within nanostructure of the coating, hence, disrupting Cassie-Baxter surface tension between the sitting liquid drop and the surrounding air. 2,4 To investigate the effect of TMOS content on surface wettability, bare fabrics were modied with coatings containing 10- (Fig. S2).…”

“…1 Discharges from industrial wastewaters generate oil-based environmental eluents (e.g., toluene) and watersoluble pollutants (e.g., dyes) whose dispersion within the food chain are also detrimental to human health. 2 In cases of oil spills, the formation of organic lms isolates the seawater from rapid oxygen exchange with the surrounding atmosphere while starving marine lives of the needed molecular oxygen sustenance. The challenges associated with effluent oil treatments using physical and chemical techniques as well as the complex nature of these effluents necessitate the design and development of functionalized lter materials capable of efficient and sustainable oil/water separation to remediate severe pollution incidents.…”

“…For example, Cao et al prepared CuO-coated superhydrophobic modified fabrics and studied its ability to degrade methylene blue aqueous solution under visible light irradiation. [35] Encouragingly, Xu et al designed a multifunctional PTM based on a copper mesh with abundant CuO nanowires exhibited a solar absorption of 93%, but the evaporation rate (0.7 kg m -2 h −1 ) was only about half that of the CuO tree system (1.42 kg m -2 h −1 ). [36] It is concluded that the high thermal conductivity of the CuO nanowire mesh caused most of the generated heat to be transferred to the bulk water below.…”

In recent years, pursuing a high evaporation rate of solar steam generation (SSG) has been the focus of research for relieving the freshwater shortage. Scientists struggled to find perfect photothermal materials while the importance of substrate during the steam generation was often overlooked. Therefore, in this work, an aerogel substrate composed of polyvinyl alcohol (PVA) and chitosan (CS) has been designed for solar steam generation. The compounded aerogels synthesized via freeze-drying method not only retain the inherent characteristics of lightweight, porosity, and high specific surface area, but also inherit the advantages of PVA in water lock effect as well as CS in moisture absorption. The obtained PVA/CS/CuO aerogel coupling with high light absorption of CuO exhibited excellent steam generation capabilities, largely benefited from the superiority of the aerogel substrate. Under 1 sun solar illumination (1 kW m -2 ), it realized an evaporation rate as high as 2.14 Kg m -2 h -1 , which is superior to recently reported semiconductor solar evaporation system. The solar-to-vapor energy conversion efficiency of 87.1% is obtained. Due to the versatility of CuO, PVA/CS/CuO aerogel not only has excellent light-to-heat conversion performance, but also has good effects in antibacterial.
