Electropolymerization and characterization of polyaniline films using a spectroelectrochemical flow cell.
A new spectroelectrochemical flow cell is presented and its capability to provide a better understanding of reaction mechanisms is illustrated with the study of the electrosynthesis and characterization of a conducting polymer, polyaniline (PANI). A spectroelectrochemical study of electropolymerization of aniline under flow conditions has been performed for the first time. The significant influence that the flow rate of feeding monomer solution has on the electropolymerization process and, consequently, on the electrochromic properties of the resulting polymer has been demonstrated.
