Nanometric titanium dioxide (TiO2) powder has been treated on the surface with octyltriethoxysilane in a supercritical carbon dioxide (scCO2) medium. The surface silanization conferred water repellency to the TiO2 powder. The effect of operating variables of the supercritical silanization process (pressure, temperature) on the surface characteristics of the material was analyzed. Finally, the e...
