Effects of resistance and capacitance on the chronoamperometry of polymer-coated electrodes as modeled by a finite elements digital simulation

A finite elements digital simulation of chronoamperometry with polymer-coated electrodes is presented. The model takes account of mass transport by diffusion and migration, and the effects of the uncompensated resistance and capacitance of the system. A graphical method for the analysis of experimen...

Description
Summary:A finite elements digital simulation of chronoamperometry with polymer-coated electrodes is presented. The model takes account of mass transport by diffusion and migration, and the effects of the uncompensated resistance and capacitance of the system. A graphical method for the analysis of experimental data was introduced and applied to electrodes coated with poly[Ru(II)(bipy) 2(4-vpy) 2] +PF − 6.
