Transient and steady state electrochemical studies of transport dynamics and equilibria in thin polymer films containing redox centers
Abstract
dc:descriptionElectron transport dynamics and equilibrium effects were studied for the ferricyanide/ferrocyanide (Fe(CN)$\sb6\sp{3-/4-}$) redox couple incorporated in partially-quaternized poly(4-vinylpyridine) (QPVP) modified electrodes in contact with potassium nitrate (KNO$\sb3$) solution. The goal was to intercompare the electron diffusion coefficient (D$\sb{\rm E}$) of the system obtained by transient and steady state electrochemical methods and to evaluate the effect of equilibrium changes in the film on the magnitude of these values. Chronocoulometry (CC), ac impedance spectrometry (AC), and a form of steady state voltammetry (SS) were the methods chosen for the intercomparative study.
