Mechanistic study on electrochemical deposition of conjugated polymers in centrifugal fields

This work presents a detailed study of the mechanism for the electrochemical deposition of conjugated polymers on anodes in centrifugal fields. The rate of the electrochemical deposition of polyaniline was affected significantly by a centrifugal acceleration force of 315 g. However, no centrifugal effects were observed on the electrochemical deposition of poly(3,4-ethylenedioxythiophene). It was found that the degree of the centrifugal effect generated depended greatly on the size of the oligomer aggregates just before their deposition. To further confirm the influence of size on electrochemical systems under centrifugal fields, we also carried out an electrochemical redox reaction using various sizes of vinylferrocene-immobilized polystylene latex particles.
