Abstract

In this study, a sol–gel method has been adopted to synthesize titanium dioxide (TiO2) particles. In order to improve the surface properties of the TiO2 particles, vinyl triethoxysilane (VTES) has been used for their modification by silanization. The particles have been characterized by FTIR, scanning electron microscope, transmission electron microscopy, and X-ray diffraction (XRD) techniques. The results confirmed that VTES had been successfully grafted onto the surface of the TiO2 particles. The TiO2 particle size was not changed by the silanization modification, remaining at 100–200 nm. XRD results have shown the crystalline phase of the TiO2 particles to be of the anatase type, and this was also unaffected by the VTES modification. Dispersion properties and suspension stability characterization of TiO2 particles showed that VTES-modified TiO2 particles have better dispersion stability and suspension stability in the dispersant of tetrachloroethylene than that of unmodified TiO2 particles.
