Abstract
The capabilities of Probe Beam Deflection (PBD) techniques for the stu dy of ion exchange in electroactive polymers are described using three polymer systems as examples. Measurements of PBD signal along with cy clic voltammograms are used to investigate the ion exchange mechanism of a polypyrrole film in 1 M HCl, and of a polyaniline film in 1 M HCl O4. The determination of the diffusion coefficient of the exchanged sp ecies is used to elucidate the ion exchange mechanism of a ladder poly mer (poly(o-phenylendiamine)) in 1 M HClO4. The advantages and disadva ntages of PBD techniques are discussed.
