Synthesis of Poly(3,4-ethylenedioxythiophene)–Platinum and Poly(3,4-ethylenedioxythiophene)–Poly(styrenesulfonate) Hybrid Fibers by Alternating Current Bipolar Electropolymerization

Langmuir, 2018
Alternating current (ac) bipolar electropolymerization of 3,4-ethylenedioxythiophene (EDOT) was performed in the presence of hexachloroplatinate ([PtCl6]2-) or poly(styrenesulfonate) (PSS). We demonstrated that both [PtCl6]2- and PSS were successfully incorporated into electrogenerated poly(3,4-ethylenedioxythiophene) (PEDOT) as dopants to offer hybrid

Preparation of Highly Conductive Gold−Poly(3,4-ethylenedioxythiophene) Nanocables and Their Conversion to Poly(3,4-ethylenedioxythiophene) Nanotubes

The Journal of Physical Chemistry C, 2007
Gold_poly(3,4-ethylenedioxythiophene) (Au-PEDOT) nanocables were synthesized at room temperature by one-step interfacial reaction of EDOT (in organic phase) and HAuCl4 (in aqueous phase) without the assistance of a surfactant, a template, or a stabilizer.

Biocatalytically Synthesized Poly(3,4-ethylenedioxythiophene)

Macromolecules, 2008
Over the past decade, poly(3,4-ethylenedioxythiophene) (PEDOT) has been one of the widely investigated conjugated polymers due to its excellent electro-optical properties. The conventional synthesis of PEDOT/PSS involves oxidation of EDOT using strong oxidants in aqueous polystyrenesulfonate (SPS) solution.

Poly(3,4‐ethylenedioxythiophene)‐based copolymers for biosensor applications

Journal of Polymer Science Part A: Polymer Chemistry, 2002
AbstractThe synthesis of 3,4‐ethylenedioxythiophene (EDOT) derivatives bearing functional groups is described. Their electrochemical characteristics were investigated with cyclic voltammetry and ultraviolet–visible spectroscopy. Various copolymers of EDOT and modified EDOT containing hydroxyl groups were electrochemically prepared.

Photoelectrochemical Properties of Poly(3,4-ethylenedioxythiophene)

The Journal of Physical Chemistry B, 2000
The photoelectrochemical properties of poly(3,4-ethylene dioxythiophene)/ poly(styrene sulfonate) in contact with an electrolytic solution containing a redox couple were studied using the theories for the semiconductor−electrolyte interface. When this polymer−electrolyte interface is illuminated with hν > Eg (gap energy) it exhibits cathodic ...

Chemical synthesis of poly(3,4-ethylenedioxythiophene)

Synthetic Metals, 1997
Abstract We have synthesised poly(3,4-ethylenedioxythiophene), (PEDOT), using FeCl3, Ce(SO4)2 and (NH4)2Ce(NO3) 6 oxidants. Greater than stoichiometric amounts of FeCl3 were required for reasonable yields. PEDOT produced using the eerie-based oxidants contained significant quantities of unidentified cerium compounds.

Poly(3,4-ethylenedioxythiophene)–clay nanocomposites

Journal of Materials Chemistry, 2008
Polymer–clay nanocomposites based on poly(3,4-ethylenedioxythiophene) (PEDOT) and montmorillonite were synthesized and characterized. Three different syntheses have been explored: (i) intercalation of 3,4-ethylenedioxythiophene (EDOT) and in situpolymerization, (ii) clay expansion and in situ oxidative polymerization of EDOT, and (iii) direct ...

Reflectance of conducting poly(3,4-ethylenedioxythiophene)

Synthetic Metals, 1999
Abstract We present the reflectance spectrum of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with PF6 with dc conductivity of 230 S/cm at room temperature, measured over a wide frequency range from 50 to 5×104 cm−1 (0.006–6 eV). The reflectance, R(ω), of PEDOT-PF6 is characterized by metal-like signatures in the infrared (IR), including high R(ω ...

Transport properties of poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate)

Synthetic Metals, 1998
Abstract The conductivity and magnetoresistance of poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDT/PSS) have been studied as a function of temperature. The room-temperature conductivities are dependent on the pH of the solutions from which the films are cast; values as high as 20 S/cm can be obtained in films cast from solutions with pH

Poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) microfibers

Synthetic Metals, 2005
Abstract The conducting microfibers of poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS) were fabricated by a wet-spinning technique. When a PEDOT/PSS aqueous solution was extruded into acetone, used as a coagulant, then dehydrated and solidified to form a fiber.
