摘要：

By the measurements of wettability, zeta potential, viscosity and sedimentation, the technique of surface chemistry was used to characterize the dispersion behavior under with and without UV irradiation condition. Photo-induced enhancement was found for the dispersion of nano-TiO2 in water. The photoaction highly improves the dispersion and stability. The effect is attributed to photogeneration of hydrophilic T1O2 surface through an investigation of the mechanism.
