摘要
Quasi-stationary determination of doping levels of polythiophenes has been successfully achieved in a wide potential window by using a modified potential-step chronocoulometric measurement of the charges consumed in oxidation and reduction processes of the polymers. Influences of experimental conditions, capacitive current-producing process and overoxidation process are discussed on the estimation of the doping levels of the polymers.
