Electrochemical impedance spectroscopy of an evolving conducting polymer dendrite in water

Antoine Baron, Sébastien Pecqueur

Deposition of PEDOT:PSS is triggered alternatively on two gold wires distant of 240 µm from each other. The gold wires are immersed in a drop of water containing 10 mM of EDOT, 1 mM of sodium polystyrene sulfonate (NaPSS) and 10 mM of benzoquinone (BQ). The growth is captured with a camera and the…
