“…Fabrics are one type of material. By lowering the energy of the surface while raising the roughness of the surface, it is possible to create a coating that is superhydrophobic upon fabric surfaces [21]. Fabrics with repellency to oils have also gained a lot of attention and the combination of both water and oil resistance qualities have grabbed even more attention.…”

The coating of various textiles, including 3D weft-knitted spacer fabrics (92% polyester -8% spandex), polyester, and cotton, is presently seen to be a great use for silica aerogels (SA). They may impart and improve various attributes to the aforementioned fabrics thanks to their exquisite porous structure, large surface area, and superior permeability. They are primarily created from three different types of precursors, namely water glass (Sodium silicate), alkoxysilanes, and orthosilicates, to produce silica, which has the chemical formula O-Si-O. They follow a conventional sol-gel manufacturing process, going through three stages: gelation, aging, and drying. They are coated onto cloth and give self-cleaning, superamphiphobicity, chemical protection, thermal insulation, and thermal comfort qualities.

Superhydrophobic textiles with multifunctional characteristics are highly desired and have attracted tremendous research attention. This research employs a simple dip-coating method to obtain a fluorine-free silica-based superhydrophobic and superoleophilic cotton fabric. Pristine cotton fabric is coated with SiO2 nanoparticles and octadecylamine. SiO2 nanoparticles are anchored on the cotton fabric to increase surface roughness, and octadecyl amine lowers the surface energy, turning the hydrophilic cotton fabric into superhydrophobic. The designed cotton fabric exhibits a water contact angle of 159° and a sliding angle of 7°. The prepared cotton fabric is characterized by attenuated total reflectance-fourier transform infrared spectroscopy, X-ray diffraction, atomic force microscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. In addition, the coated fabric reveals excellent features, including mechanical and chemical stability, superhydrophobicity, superoleophilicity, and the self-cleaning ability. SiO2 nanoparticles and octadecylamine-coated cotton fabric demonstrate exceptional oil–water separation and wastewater remediation performance by degrading the methylene blue solution up to 89% under visible light. The oil–water separation ability is tested against five different oils with more than 90% separation efficiency. This strategy has the advantages of low-cost precursors, a simple and scalable coating method, enhanced superhydrophobicity and superoleophilicity, self-cleaning ability, efficient oil–water separation, and exceptional wastewater remediation performance.

“…Notably, it offers exceptional water and chemical resistance, guaranteeing the durability and longevity of the coated layer, and low surface tension (<20 mN/m), making it highly effective in reducing the surface energy of the substrate. Moreover, its flexibility, affordability, biocompatibility, and thermal stability further contribute to its appeal as a superior choice for sustainable and long-lasting superhydrophobic surfaces. , For instance, Zhu et al developed superhydrophobic cotton by harnessing the synergistic effect of rGO-TiO 2 /QAS-SiO 2 dual nanoparticles. The optimal dual-particle coating was effectively bound to the textile surface by using PDMS as a binder.…”

This study introduces a novel superhydrophobic coating applied to the fabric surface through spray coating of the Al 2 O 3 /MMT nanocomposite and PDMS polymer to enhance the surface roughness and reduce the surface tension, respectively. The as-prepared coating exhibits a remarkable superhydrophobic property with a water contact angle (WCA) of ∼174.6° and a water sliding angle (WSA) < 5°. Notably, the fabric demonstrates a self-cleaning property through removing dust and dirt via adhering to water droplets. Moreover, the insignificant loss of WCA (3.2 and 1%) after exposure to alkaline and acidic media for 10 days verifies the promising chemical stability of the coated layer, whereas WCA > 160° after 24 h of immersion in various organic solvents further indicates the layer resistance. Besides, the layer sustains WCA of 174.5, 172.5, and 168.45° after 1 month of air exposure, ultrasonic washing, and 50 cycles of home laundry. The mechanical resistance of the fabric was verified by maintaining a WCA of 158.73° after 200 abrasion cycles. Also, the layer exhibits thermal resistance with <4.1% of WCA loss in the temperature range of −10 to 180 °C. Additionally, the superhydrophobic coating excels in oil–water separation, achieving >99% separation efficiency for various oils. These exceptional properties position the fabric for diverse applications, including protective clothing, outdoor gear, medical textiles, and sportswear, emphasizing its versatility and novelty in the realm of superhydrophobic materials.
