“…The second one was a capillary action, which was a surface phenomenon in which oil flowed freely into small areas. The lower surface energy, computed using the (OWRK) technique, was found to be in the range of (20.96 ± 0.19-34.33 ± 0.60) mN.m À1 , close to the surface energy of oils (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) mN.m À1 but much lower that of water (72 mN.m À1 ), leading to the sorbents' hydrophobicity, with a water contact angle of up to145.1 ± 0.42°. Hence, the 3D weft-knitted spacer fabrics' oil absorption capacity mainly depended on oil properties, fabric properties, nanoporous SiO 2 aerogel properties, and spaces inside and between fibers and fabrics.…”

“…18,19 Hydrophobicity, oleophilicity, absorption capability, resilience, better oil/water separation, and reusability are all desirable qualities in an oil sorbent material. [20][21][22] Due to unique advantages such as outstanding chemical and mechanical competencies, as well as easy processing, synthetic polymer materials such as polyester (PET) are now commonly employed as oil sorbents. [23][24][25] PET also possesses hydrophobic and oleophilic properties, making it a viable material for oil spill remediation.…”

Silica aerogels were made from tetraethylorthosilicate by the sol-gel method and coated on the 3D weft-knitted spacer fabrics (WKSFs) to compare the interaction of the silica aerogel coating with five various concentrations. SEM, FTIR-ATR, surface roughness, surface energy, and BET analysis were used to observe and characterize the surface morphology, molecular interaction, surface changes, surface tension, and specific surface area of fabric samples or sorbents. Consequently, this study investigated the wettability, oil absorption capacity, oil retention capacity, and reusability of untreated and treated 3D WKSF sorbents. The outcomes exposed the excellent hydrophobic and oleophilic properties of all treated 3D WKSF sorbents, showing a greater water contact angle of 145.1 ± 0.42°, and an oil absorption and retention capacity of (7.87 ± 0.09 g/g and 7.53 ± 0.06 g/g) and (89.98 ± 0.79% and 92.48 ± 0.56%) for vegetable oil and engine oil, respectively, with notable reusability, most particularly for sorbent 5, due to the higher silica aerogel add-on %, pore diameter, and pore volume. The findings verified that the chemical composition and fabric structure played an important role in the tremendous hydrophobic and oleophilic behavior. The statistical study on specific surface area, pore diameter, pore volume, surface roughness, water contact angle, oil contact angle, oil absorption capacity, and oil retention capacity also revealed that treated fabrics performed significantly ( p < 0.05) in hydrophobic and oleophilic features at the 0.05 level. Hence, these fabrics can be used in industrial usages that need hydrophobic and oleophilic qualities.

“…39 As the SA add-on percentage, pore volume, and pore diameter increased, the oil absorption capacity increased. 38 Therefore, an improved ability to pick up oil was attained due to the hydrophobic interaction and Van der Waals force between the 3D WKSFs and the oils. 9 The oil retention capacity (%) of UCSs and CSs (CS 1, CS 2, CS 3, CS 4, and CS 5) of 3D WKSFs was calculated after 24 h dripping, and the outcomes are shown in Figure 6 and Supplementary Material Table S3 The findings for both UCSs and CSs of 3D WKSFs were that the engine oil retention capacity was greater than the vegetable oil.…”

[37][38][39][40] These 3D fabrics are also treated as eco-friendly sorbent materials. Furthermore, these 3D fabrics perform better in several areas as a multifunctional textile material than nonwoven, woven, and conventional knitted fabrics.…”

This study investigated the thermal, mechanical, and oil absorption-retention properties at various temperatures (20°C, 30°C, 40°C, 50°C, and 60°C) of three-dimensional (3D) weft-knitted spacer fabrics with optimal performance of silica aerogel coating that demands exceptional attention. Silica aerogels and (silica aerogels + poly(vinyl-alcohol)) sols were prepared and coated on 3D weft-knitted spacer fabrics to study and compare the basic properties, i.e. thermal resistance, thermal conductivity, tensile strength, initial modulus, compression, bending rigidity, wettability, oil absorption, and retention capacity. The scanning electron microscopy and Fourier transform infrared spectroscopy studies were completed to understand the influence of both coatings on 3D weft-knitted spacer fabrics such as surface morphology and molecular interaction. The tensile, bending, and compression tests of 3D weft-knitted spacer fabrics were accomplished to check their durability, bendability, and compressibility. All the coated samples (both silica aerogels and (silica aerogels + poly(vinyl-alcohol))) showed greater thermal resistance (0.0971 ± 0.0003 m2 KW−1 and 0.0912 ± 0.0005 m2−1KW−1) and the lower thermal conductivity would be (0.0309 ± 0.0001 Wm−1 K−1 and 0.0329 ± 0.0002 Wm−1 K−1) instead of (0.0329 ± 0.0002 Wm−1 K−1 and 0.0329 ± 0.0002 Wm−1 K−1) with better thermal stability than the uncoated samples, most specifically coated sample 5. Besides, coated sample 5 exposed higher oil absorption ((7.91 ± 0.06 g/g and 7.88 ± 0.06 g/g) and (7.56 ± 0.04 g/g and 7.53 ± 0.04 g/g)) and retention ((90.10 ± 0.53% and 89.07 ± 0.55%) and (92.47 ± 0.49% and 91.43 ± 0.47%)) capacity for vegetable and engine oil in all conditions, especially at 40°C. The outcomes demonstrated that both coatings played a vital role in the thermal, mechanical, and wettability properties of 3D weft-knitted spacer fabrics with statistically significant performance ( p < 0.05). Moreover, these new types of sorbents (3D weft-knitted spacer fabrics) have better consequences in most cases than conventional knitted, woven, and nonwoven sorbents. Hence, these 3D weft-knitted spacer fabrics could be used for industrial applications as eco-friendly and multifunctional oil sorbent materials.
