Abstract
A high-concentration dispersion with nanometer TiO2 particles has been fabricated by a hyperdispersant. The particle distribution, composition, viscosity, thermal stability were investigated by transmission electron microscopy, and laser size analyzer, x-ray diffraction, rheometer, differential thermal analysis, and thermogravimetry, respectively. The mean particle size of the nano-TiO2 concentrated dispersion was 72 nm with an especially narrow distribution, and near to monodispersion. The viscosity of 55 wt% nano-TiO2 dispersion is 30 mPa·s at 344 s−1. The dried dispersion composition made from the nano-TiO2 and the hyperdispersant has good thermal stability.
