Area of Science:

  • Electrochemistry
  • Materials Science
  • Analytical Chemistry

Background:

  • Traditional reference electrodes often contain liquid electrolytes, posing challenges for miniaturization and stability in all-solid-state devices.
  • Conducting polymers (CPs) offer potential for solid-state electrochemical applications due to their tunable properties.

Purpose of the Study:

  • To develop novel, solution-free pseudo-reference electrodes compatible with all-solid-state potentiometric sensors.
  • To investigate the performance of conducting polymers, specifically polypyrrole (PPy) and poly(3,4-ethylenedioxythiophene) (PEDOT), in these electrodes.
  • To evaluate different electrode constructions for stability and resistance to common interferences.

Main Methods:

  • Fabrication of conducting polymer-based electrodes with two distinct arrangements: solely CP-based and CP with a poly(vinyl chloride) (PVC) outer membrane.

  • Systematically varied doping strategies within the CP layers, including mobile and immobilized anions, and surfactant doping.
  • Characterization using electrochemical impedance spectroscopy and chronopotentiometry.

    • Main Results:

    • Potentials recorded for initial systems were largely independent of electrolyte concentration.
    • The most stable potentials were achieved with PEDOT or PPy doped with poly(4-styrenesulfonate) anions, encased in a PVC membrane containing ion exchangers and Ag/AgCl.
    • This optimized configuration demonstrated significantly reduced sensitivity to redox and pH interferences compared to other designs.

    Conclusions:

    • A robust, solution-free pseudo-reference electrode construction based on conducting polymers has been successfully developed.
    • The optimized electrode design offers enhanced stability and reduced susceptibility to common electrochemical interferences, making it suitable for all-solid-state potentiometric applications.
