Electropolymerization of an Immiscible Monomer in Aqueous Electrolytes Using Acoustic Emulsification

This paper reports on the novel electropolymerization of an immiscible monomer, such as 3,4-ethylenedioxythiophene (EDOT), in aqueous electrolytes using acoustic emulsification. This new methodology has many practical advantages and characteristics: (a) the formation of stable monomer droplets in aqueous electrolytes without added surfactants using ultrasonic treatment; (b) very smooth electropolymerization in aqueous electrolytes via the direct electron transfer between the electrode and the immiscible monomer droplets; (c) good conductivity after doping of the polymer film formed.
