Sustainable and cost-effective functionalization of textile surfaces with Ag-doped TiO2/polysiloxane hybrid nanocomposite for UV protection, antibacterial and self-cleaning properties

• Improved photocatalytic activity of TiO 2 by Ag doping. Co-operative synergism polysiloxane backbone, , and textile surface. Semiconductor-metal-semiconductor heterojunction on the /polysiloxane/Ag/textile nanocomposite Outstanding multifunctional antibacterial, UV protective self-cleaning properties nanocomposite. Excellent wash durability In this work, was incorporated into surface cotton fabrics an in situ sol–gel/hydrothermal approach. Dimethyloctadecyl [3-(trimethoxysilyl) propyl] ammonium chloride (SiQAC) added as a bio-barrier Si precursor to enhance synergistic effect/binding fabric. A small amount silver nitrate (AgNO 3 ) produce Ag-doped -coated fabric during hydrothermal treatment. The treated samples were characterized scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDS), Fourier transform infrared spectroscopy (FT-IR) diffraction (XRD) determine morphology, chemical composition, bonding crystal structure, respectively. These results confirmed successful application well-dispersed SiQAC functionalized with + exhibited superior antibacterial against Escherichia coli Staphylococcus aureus very good protection excellent performance, which maintained even after repeated washings. resistance newly developed -based hybrid nanocoating attributed formation matrix, served anchoring site for through Si–O–Ti bonds. enhanced coating Ag/AgCl/TiO heterostructure, is promising interface engineering -modified
