Abstract

The use of nanomaterials in textile area already showed considerable potential with economic and environmental benefits. In the present study, Ag-TiO2 and Ag-TiO2/reduced graphene oxide powders were prepared by a combined chemical/thermal approach followed by deposition onto flax samples by immersion from ethanol solution. TiO2 P25 (Degussa)-coated flax blank sample was obtained and examined for comparison. The morpho-structural properties of flax samples were investigated by Scanning Electron Microscopy (SEM), X-ray powder diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The transmittance measurements of the coated flax samples were performed and the ultraviolet (UV) light-shielding ability was evaluated. TiO2 P25 coated flax sample showed a good UV light-shielding property (UPF = 15.536)..
