Study of synthesis and application of titanium dioxide TiO2 nanoparticles on polyester cotton P C textiles for imparting multifunctional properties

Abstract

In this work, titanium dioxide (TiO2) nanoparticles have been prepared through bottom-up chemical reaction method using sol-gel technique with various starting materials such as Titanium tetraisopropoxide (TTIP), Tetrabutyl orthotitanate (TBOT) and Titanium tetraethoxide (TTE). Nanoparticles prepared using these precursors have also been further subjected to modifications using the modifier of (3-Aminopropyl) triethoxysilane and the cross-linker hydrogen silicone oil. The six varieties of TiO2 nanoparticles prepared before and after chemical modifications (Tu1, Tu2, Tu3, Tm1, Tm2 and Tm3) were subjected to characterisation for nanoparticle size and distribution using Particle Size Analyser (PSA), crystal structure information using X-ray Diffraction spectroscopy (XRD), chemical information using Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy (ATR- FTIR), the surface morphology of textile substrate was studied by Field Emission Scanning Electron Microscopy (FESEM) and the elemental composition of the particles through Energy Dispersive X-ray spectroscopy (EDX) analytical technique. newline newline newline
