“…Since the first synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT) in 1980 by Bayer [4], this polymer has been widely studied due to its high conductivity, interesting electrical and spectrochemical properties associated with its low band gap, as well as electrochromic and antistatic properties [5][6][7].…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT AbstractDeep eutectic solvents are evaluated as media for the electropolymerisation of 3,4-ethylenedioxythiophene (EDOT) for the first time. PEDOT modified glassy carbon electrodes (GCE) were characterised by cyclic voltammetry, electrochemical impedance spectroscopy and scanning electron microscopy. PEDOT modified GCEs prepared from choline chloride-urea (reline) and choline chloride -ethylene glycol (ethaline) exhibited interesting electrocatalytic and morphological characteristics. Fixed potential sensing of ascorbate at 0.0 V showed a greater electrocatalytic effect, significantly higher sensitivity and lower detection limit than at hitherto reported PEDOT modified electrodes.

“…The solubility problem was circumvented with a water-dispersible anionic polyelectrolyte, poly(styrene sulfonate) (PSS), used as a charge-balancing counterion during polymerization. The PEDOT/PSS composite is believed to be a colloidal suspension in which PEDOT chains decorate segments of higher-molecular-weight PSS chains [13][14][15]4]. This polymer complex displays good filmforming properties, high electrical conductivity and transmission of visible light, and excellent chemical (environmental) stability owing to the high regularity of the polymer backbone [7,[16][17][18][19].…”

The fundamental properties of pure poly(3,4‐thylenedioxythiophene) (PEDOT), one of the most common electrically conducting organic polymers, are the key to the development of more prominent applications in which PEDOT and its derivatives can be utilized. Conducting molecular complex of PEDOT with silica was synthesized in the presence of charged silica template by the in situ biomimetic polymerization. To remove silica from PEDOT/template complex, hydrofluoric acid was used to etch silica particles. The electrochemical, thermal, and optical properties of pure PEDOT recovered were investigated in comparison with those of EDOT monomer or PEDOT with template by using UV–vis–near–IR spectra, cyclic voltammetry, thermogravimetric analysis, and fluorescence spectra.

“…Partial oxidation of the sulfur of the polymer backbone and the decomposition of the counter ion (FeCl − ) resulting in decrease of conductivity [11]. It is obvious that the difference of σ of the two similar samples at each T the two curves of Figure 1, heated with the same rate but under different environments can give us an estimation of the role of oxygen and moisture contained in the atmospheric air on the structure of PE-DOT:PSS.…”

“…TGA measurements and FTIR spectroscopy of PE-DOD:PSS films revealed that there is no significant chemical changes up to the temperature of 523 K and there is an almost steady content of water for a wide range of temperatures [1]. Different oxidative reactions of the thiophene ring have been proposed [11] and for temperatures above 533 K PSS degrades reducing the PE-DOT:PSS bulk conductivity.…”
