The final, formatted version of the article will be published soon.

    The author has previously established an electrochemical technique, namely potential-step chronocoulometry (PSC), enabling the precise control of the doping state and accurate quantitation of the doping level (charge density, i.e., the number of injected charges per unit volume) in conducting polymers. This technique was used to analyze the correlation between the doping level and charge-transport properties of such polymers and evaluate the performance of organic thermoelectric materials, which have recently attracted considerable interest as new energy materials, in relation to their charge density. The present review summarizes representative studies using PSC to analyze the charge-transport and thermoelectric properties of conducting polymers in relation to charge density.

    Keywords: conducting polymer, Potential-step chronocoulometry, Charge density, Doping level, charge transport, Thermoelectric property
