Abstract
<p>A conducting polymer works as an ion-to-electron transducer in which its redox reaction involves doping/undoping ions, and the conducting polymer-coated electrode has been studied as an inner reference electrode in all-solid ion-selective electrodes, all-solid ISE. Recently, some conducing polymer-inks have been utilized for a disposable printing all-solid ISE. However, the low stable and low reproducible electrode potential in a conducting polymer-coated electrode have been a long-standing problem for practical applications. Our previous work has reported that the partially 50 % oxidized conducting polymer in applying the formal potential has the most redox buffer capacity and shows stable electrode potential. In the present work, two commercially available poly(3,4-ethylenedioxythiophene), PEDOT, inks were examined to evaluate the formal potentials and the oxidation ratio based on the ultraviolet-visible absorption spectra recorded in applying a potential. Principal component analysis (PCA) was useful for extracting the potential-depending spectra from absorption spectra involving the other component’s absorption.</p>
