title: An analysis of current transients during electrophoretic deposition (EPD) from colloidal TiO2 suspensions.
abstract: This is a simple quantitative analysis of the electrical current transients recorded during the electrophoretic deposition (EPD) of TiO(2) particles from ethanol-based suspensions in which the linear correlation between the mass deposited and the charge passed was verified experimentally. Using this experimental knowledge as our starting point, we were able to test a simple electrical model of a deposition cell for its consistency with electrical current density data measured during EPD. Assuming that the background electrochemistry was controlled resistively rather than diffusively, we then tentatively exploited the electrochemical data to gain information on the structure of the deposit during its growth.
