Electrochemical and spectroscopic characterization of polyalkylenedioxythiophenes

Recovery and characterization of pure poly(3,4‐ethylenedioxythiophene) via biomimetic template polymerization

“…Figure 4 shows comparative cyclic voltammograms (CVs) obtained from the potential dynamic mode for (a) EDOT monomer and (b) PEDOT without template in TBAPF6 THF solution at room temperature. Similar CVs of PEDOT have been already reported by Heinze and co-workers [14] and Zotti et al [32], though in the latter case thin PEDOT films have mainly been studied. The CV of EDOT (Fig.…”

“…The CV of EDOT (Fig. 4a) showed well-defined anodic (oxidation) peaks (E p,a ¼ À0.517 and E p,a ¼ 1.49 V), cathodic (reduction) peaks (E p,c ¼ 0.112 and E p,c ¼ À0.647 V) on the reverse scan [14,33]. The anodic part of the voltammogram exhibits the feature common to most polythiophenes and is similar to that reported previously.…”

“…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].…”

Morphological characterization and analytical application of poly(3,4-ethylenedioxythiophene)–Prussian blue composite films electrodeposited in situ on platinum electrode chips

“…The choice of inorganic and organic components for preparation of these composite materials is based on the excellent stability of the PEDOT layer in aqueous solution and its doped state [35][36][37], and the electrocatalytic activity of PB [38,39], respectively. The PEDOT organic component is in its conducting state in the potential region where the PB inorganic component exhibits its good electrocatalytic activity.…”

Electrodes Modified with Composite Layers Based on Poly(3,4-ethylenedioxythiophene) as Sensors for Paracetamol

“…PEDOT is one of the most promising conducting polymers due to its characteristics, namely: reversible doping state, 9 excellent stability, 10,11 low band-gap (high conductivity), 12,13 and electrochemical properties. 14,15 For these reasons, PEDOT is an ideal candidate for sensor applications. 16,17 Due to its low solubility in water, PEDOT films are usually synthesized in organic media or in aqueous solutions with surfactants.…”
