Abstract:Different concentration of TiO2 sols (10-40% g/l) synthesized by titanium tetra isopropoxide (TTIP). PET fabric dipped in prepared sols and sol-gel process accomplished at low temperature. Particle size of synthesised Nano TiO2 determined by particle size analyzing and morphological characteristics of treated samples analysed by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and crystalline structure of synthesis particles by X-ray diffraction method (XRD). Methylene blue (MB) used for photocatalytic evaluation. Treated samples exposed with UV light in a methylene blue bath and the amount of discoloration determined by UV-visible spectrophotometery method. Results showed that increasing the amounts of TiO2 on the surface of PET fabric improves the photocatalyic activity.
