Abstract：

In order to prepare stable TiO2 aqueous suspension for electrophoretic deposition, PEI as a dispersant was added into the water-based suspension of TiO2. Zeta potential, viscosity, particle size and stability were tested to study the effect of the dispersant on dispersing of TiO2 water suspension. The results showed that by adding 0.6%~3%dwb amount of dispersing agent into the suspension can obtain high stability, high dispersion, and low viscosity suspension which was suitable for cathodic deposition.
