This research delineates the pioneering development of a superhydrophobic cotton textile, ingeniously integrated with a three-dimensional graphene-Ag/TiO₂ aerogel. The study meticulously details the fabrication process, structural characterization, and diverse industrial applications of this advanced textile. The fabric demonstrates exceptional hydrophobicity, evidenced by a water contact angle (WCA) of 161.8°. Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), X-ray Diffraction (XRD), Raman spectra, and Fourier Transform Infrared Spectroscopy (FTIR) substantiate the micromorphological and chemical alterations of the cotton surface, highlighting the successful reduction of graphene oxide (GO) and incorporation of polydimethylsiloxane (PDMS), TiO₂, and Ag nanoparticles. The fabric’s antibacterial efficacy is rigorously established, boasting an impressive antibacterial rate that surpasses 99.99 % against E. coli and S. aureus. Additionally, the fabric demonstrates its capability to discern between oil and water with remarkable finesse, showcasing a separation efficiency that exceeds 98 %, even under extreme chemical conditions. The textile also exhibits excellent self-cleaning, washing, and chemical durability, alongside robust antistatic properties. Despite a marginal decrease in air permeability relative to raw cotton, the fabric’s multifunctional capabilities significantly compensate for this trade-off. The unique three-dimensional architecture of the hybrid graphene-Ag/TiO₂ aerogel (AT-HGA) modified cotton marks a substantial advancement in bio-based material science, with broad potential applications in functional garments, medical textiles, and various industrial sectors.
