Green synthesis of superhydrophobic cotton filters using Pistacia atlantica gum for efficient oil and water separation

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 4, 2025

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) TiO2 nanoparticles were coated the NPS reagent. Subsequently, cotton fabrics dip-coated separately NPS, NPS-BCur, NPS-TiO2, resulting in fabrication of superhydrophobic filters water contact angles (WCA) exceeding 150°. The reagents thoroughly characterized FT-IR, XRD, TGA, SEM, X-ray mapping, WCA measurements. demonstrated exceptional performance separating oil-water mixtures, achieving separation efficiencies 91-98.6%. Even after 20 recycling cycles, negligible changes observed efficiency. use natural materials, eco-friendly synthesis, high durability, outstanding underscore sustainability practicality these fabrics.

Abstract In recent years, the research topic of hydrolysis polyethylene terephthalate (PET) using bioenzymes has attracted a lot attention and can be divided into two parts: enzymatic surface modification polyester fibres biodegradation PET waste. The high crystallinity makes enzyme study very challenging compared to Deep eutectic solvents (DES) create favourable environment for proteins represent new generation biodegradable solvents. However, there are few studies on use DES enhance degradation. For these reasons, we attempted hydrolyse with DES-activated enzymes increase yield thus improve modification. We investigated effects type, molar ratio concentration hydrolysis, utilizing betaine choline chloride as hydrogen bond acceptors polyol donor. Humicola insolens cutinase (HiC) is used main biocatalyst fabric hydrolysis. results showed that low (20% v/v) deep (betaine:sorbitol; 1:2 ratio) induced significant in (more than 1.5 times). boosting effect primarily resulted from benefits itself rather superimposition individual components. Further revealed HiCexhibited relative activity stability at concentrations DES. addition, spectral analyses effectively preserved structure HiC. Our work sheds light development efficient sustainable method HiC fabric, opening up opportunities possibilities comprehensive utilization bio-modification fabric.
