Abstract

Anion exchange in anodically synthesized free-standing membranes of polypyrrole tosylate was studied by a combination of spectrophotometry, ac impedance, potentiometry, and electrochemical techniques. The short-time diffusion profiles could be analyzed in terms of a semiinfinite planar diffusion model. The apparent diffusion coefficients extracted via application of this model span the 10** minus **1**2-10** minus **1**0 cm**2/s range. These values are compared with the results of recent measurements in other laboratories on othr polymer systems, including polyacetylene.
