Influence of Dispersants on Dispersion Stability of TiO2 Suspensions
TiO2 nanoparticles are prone to aggregate in aqueous solution, which limits its extensive application. Several researches have been carried on the stability of TiO2 suspensions. In this study, four common dispersants including ethanol, tetrahydrofuran (THF), polyvinylpyrrolidone (PVP), and sodium hexametaphosphate (SHMP) have been chosen to detect their effects on stability of TiO2 aqueous suspensions. The experimental results showed that THF and SHMP were efficient dispersants for TiO2 nanoparticles in aqueous solution.
