Abstract

Electrodeposition of the conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT) in deep eutectic solvents (DES), prepared by the simple mixing and heating of an H-bond acceptor, choline chloride and H-bond donors such as urea, ethylene glycol and glycerol, is described. The \PEDOT\ modified glassy carbon electrodes prepared in different \DES\ and in the presence of conventional aqueous surfactants or \HClO4\ media were characterized during and after growth by electrochemical and quartz crystal microbalance studies. \PEDOT\ synthesized in the best performing \DES\ medium, choline chloride
