| Summary: | Abstract In this study, a novel hydrophobic polysulfide (NPS) reagent was synthesized using Pistacia atlantica gum and sulfur powder under hydrothermal conditions. Boehmite (γ-AlOOH) functionalized with curcumin (BCur) and TiO2 nanoparticles were coated with the NPS reagent. Subsequently, cotton fabrics were dip-coated separately with NPS, NPS-BCur, and NPS-TiO2, resulting in the fabrication of superhydrophobic filters with water contact angles (WCA) exceeding 150°. The reagents and coated fabrics were thoroughly characterized using FT-IR, XRD, TGA, SEM, X-ray mapping, and WCA measurements. The filters demonstrated exceptional performance in separating oil-water mixtures, achieving separation efficiencies of 91–98.6%. Even after 20 recycling cycles, negligible changes were observed in WCA and separation efficiency. The use of natural materials, eco-friendly synthesis, high durability, and outstanding separation performance underscore the sustainability and practicality of these superhydrophobic cotton fabrics. |
