Sonochemical fabrication of nanocryatalline titanium dioxide (TiO2) in cotton fiber for durable ultraviolet resistance
Abstract
A facile approach to in situ sonosynthesis and fabrication of nanocrystalline titanium dioxide (TiO2) in cotton fiber via low temperature sol-gel technique for superior ultraviolet resistance has been studied. Tetrabutyl titanate (TBT) was used as a precursor and ultrasonic cavitation was applied to synthesis TiO2 at low temperature followed by a simultaneous deposition in cotton fibers. Functionalized cotton fibers were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive Spectroscopy (EDS), Thermo gravimetric Analysis (TGA), UV-Visible spectroscopy (UV-Vis) and X-ray diffraction (XRD) analysis. Ultraviolet resistant property of TiO2 assembled cotton fiber and was examined by UV transmittance analyzer. The results indicate that crystal TiO2-Nps at size between 17 and 19 nm include anatase and rutile structure was successfully synthesized and deposed in mesopores, lumen and surface of the cotton fibers. Durable protection against ultraviolet radiation was obtained, which exhibit significant prospect of using low temperature sonochemical synthesis of metal oxides nanoparticles and deposition in porous textiles for a broad range of functional application.
