Obvious enhancement in electrochemical capacitive properties for poly(3,4-ethylenedioxythiophene) electrodes prepared under optimized conditions

How to switch from a poor PEDOT:X oxygen evolution reaction (OER) to a good one. A study on dual redox reversible PEDOT:metallacarborane

“…The mechanism for polymerization can be speculated as the oxidation of the monomer generating a radical that could lead to polymer formation by the release of a proton. 2…”

“…The most commonly employed and commercially available COP is PEDOT:PSS where polystyrene sulfonate acts as the doping anion. PEDOT:PSS polymers are employed as thermoelectric materials having high efficiency, 2 as the electrolyte in polymer electrolytic capacitors, 3 as flexible organic cells, 4 as light emitting diodes 5 and as an alternative to indium tin oxide. 6 In contrast, redox polymers are those which alter their electrochemical properties with a change in the oxidation state in a reversible manner.…”
