Preparation and Modification of Nanometer TiO₂ with High Reflectivity

Abstract:

In order to prepare high reflectivity titanium dioxide, by sol - gel method after nano-titanium dioxide powder, which silane coupling agent KH-570 covering it and make its surface modification.When the reaction temperature is 40 °C, drop accelerated rate 1.5mL/min, calcination temperature about 600 °C, got titanium dioxide with relatively high reflectivity and particle size in around 65 nm.When the amount of the silane coupling agent is 0.5%, the pH of reaction system is 6.5, and the reaction time was 1.5h, the nano-modified titanium dioxide particles with high reflectance.
