“…We attribute this peak to an irreversible oxidation of the PEDOT coating, as observed elsewhere in PEDOT electro-synthesis literature. 39,40 Voltammetric deposition of EDOT without the presence of a counter ion in solution does not form a coating or generate an oxidative current (Figure S-1). …”

A Nafion and PEDOT-containing composite polymer has been electropolymerized on carbon-fiber microelectrodes with the goal of creating a mechanically stable, robust, and controllable electrode coating that increases the selectivity and sensitivity of in vivo electrochemical measurements. The coating is deposited on carbon-fiber microelectrodes by applying a triangle waveform from + 1.5 V to −0.8 V and back in a dilute solution of ethylenedioxythiophene (EDOT) and Nafion in acetonitrile. Scanning electron microscopy (SEM) demonstrated that the coating is uniform and ~100 nm thick. Energy-dispersive x-ray spectroscopy (EDX) demonstrated that both sulfur and fluorine are present in the coating, indicating the incorporation of PEDOT (poly(3,4-ethylenedioxythiophene) and Nafion. Two types of PEDOT:Nafion coated electrodes were then analyzed electrochemically. PEDOT:Nafion-coated electrodes made using 200 µM EDOT exhibit a 10–90 response time of 0.46 ± 0.09 seconds vs. 0.45 ± 0.11 seconds for an uncoated fiber in response to a 1.0 µM bolus of dopamine. The electrodes coated using a higher EDOT concentration (400 µM) are slower with a 10–90 response time of 0.84 ± 0.19 seconds, but display increased sensitivity to dopamine, at 46 ± 13 nA/µM, compared to 26 ± 6 nA/µM for the electrodes coated in 200 µM EDOT and 13 ± 2 nA/µM for an uncoated fiber. PEDOT:Nafion-coated electrodes were lowered into the nucleus accumbens of a rat, and both spontaneous and electrically evoked dopamine release were measured. In addition to improvements in sensitivity and selectivity, the coating dramatically reduces acute in vivo biofouling.

Electro-generations of conducting polymers are fast processes through a complex mechanism of parallel reactions giving mixed materials. The films are three-dimensional electrochemical reactors: reactive macromolecules, ions, and solvent. The film composition and its related properties reviewed here change by oxidation/reduction along several orders of magnitude under control. One reaction shifts different properties (multifunctionality). In one device several reaction driven tools, actuators and sensor, work simultaneously (full integration

“…In its well‐known study, the one of most attractive properties of PEDOT is that its properties can be tuned by grafting various functional groups. Therefore, different functionalized PEDOT derivatives have widely been studied for their potential different applications in the most recent literature . Sallé and co‐workers synthesized three fluorinated functionalized 3,4‐ethylenedioxythiophene (EDOT) derivatives, and the corresponding fluorinated PEDOT films with dry and chemically immobilized lubrication properties were obtained by electropolymerization .…”

Poly(2-chloromethyl-2,3-dihydrothieno [3,4-b][1,4]dioxine), a chloromethyl functionalized poly(3,4-ethylenedioxythiophene) derivative (PEDOT-MeCl), was synthesized electrochemically via the potentiostatic polymerization of its monomer in dichloromethane solution containing suitable tetrabutylammonium tetrafluoroborate, then it was used for the characterization of film properties and the fabrication of electrochemical sensor. The properties of the resulting PEDOT-MeCl film were characterized by different methods such as cyclic voltammetry, electrochemical impedance spectroscopy, Fourier transform infrared and ultraviolet-visible techniques, scanning electron microscope, and thermogravimetric analysis. The PEDOT-MeCl film displayed a good reversible redox activity, remarkable capacitance properties, good thermal stability, rough, and porous structure, especially fluorescent spectra indicated that PEDOT-MeCl was a blue-emitter with maximum emission centered at 396 and 398 nm. Finally, the PEDOT-MeCl film was employed for the fabrication of the sensing electrode, and dopamine was chosen as a model analyte for the application of the electrochemical sensor. Results indicated that the PEDOT-MeCl film as sensing interface was feasible, and studies of these film properties were very beneficial for studying properties and applications of other poly(3,4-ethylenedioxythiophene) derivative films.
