Abstract
Abstract Electrical variations as an aperiodic oscillation were generated across polypyrrole chemically polymerized on polycarbonate membrane filters, separating two electrolyte solutions, one containing an electron donor and the other an electron acceptor. It was found that the aperiodic oscillations were created by stirring of the solutions and were amplified by salt concentration differences across the membrane. Speculation that the aperiodic oscillations reflect the differences in electron and ion transfer rate between reduced and oxidized states of the polypyrrole membranes motivated and guided the simulation portion of this study. The aperiodic oscillation behavior was successfully reproduced by the Monte Carlo simulation of a model based on the propagation mechanism of a conductive zone in conducting polymers.
