“…Other electrode substrates have been used relatively little, exemplified by gold in an electrochemical quartz-crystal microbalance (ECQM) [8] or glassy carbon [9]; in addition, different assemblies containing PEDOT obtained in combination with carbon nanotubes [10] or carbon nanofibres [11] have also been reported. PEDOT has been applied to the detection of several important chemically and biologically relevant compounds such as hydrogen peroxide [12,13], nitric oxide [14], dopamine [9] and ascorbic acid [15].…”

Characterisation of the modified electrodes was done by cyclic voltammetry and electrochemical impedance spectroscopy and the stability of the polymer films was probed. The coated electrodes were tested for application as hydrogen peroxide sensors, by oxidation and reduction. A novel polymer film was also formed by modification of CFE by co-electropolymerisation of EDOT and the phenazine dye neutral red (NR) -(PEDOT/PNR) with a view to enhancing the properties for sensor applications. It was found that hydrogen peroxide reduction at the PEDOT/PNR coated electrodes could be carried out at a less negative potential, the sensor performance comparing very favourably with that of other polymer-modified electrodes reported in the literature.

“…13 Recently, it has been found that the high conductivity of PEDOT-PSS films can be raised by several orders of magnitude by adding dielectric solvents such as dimethyl sulfoxide (DMSO), and N,Ndimethylformamidein. [14][15][16][17][18] It is believed that this helps to align the PEDOT chain and enhances the carrier transport. The extra degrees of freedom that come from adding both DMSO and PSS create new opportunities for tailoring the transport properties of PEDOT polymers, for the development of thermoelectrical materials.…”

The thermoelectric performance of synthetic conductive polymers, poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT/PSS), is explored. The effects of the dielectric solvent, dimethyl sulfoxide (DMSO), and of the ratio of PEDOT to PSS in the polymeric PEDOT/PSS thin films were studied systematically. Within the parameter range studied in this work, the variation of electrical conductivity overwhelmed the variation of the Seebeck coefficient, and the optimal power factor is basically determined by the highest electrical conductivity, because the Seebeck coefficient remains small over a wide range of DMSO concentrations and PEDOT:PSS ratios.
