Thermoelectric Performance of Poly(3,4-ethylenedioxythiophene): Poly(styrenesulfonate)

Chinese Physics Letters, 2008
Thermoelectric (TE) performances are systematically investigated for the pellets of poly(3,4-ethylenedioxythio-phene):poly(styrenesulfonate) (PEDOT:PSS) with different organic additives and heating process as organic TE materials. The electrical conductivity, Seebeck coefficient and thermal conductivity versus temperature are determined, respectively ...

“Click”-functionalization of conducting poly(3,4-ethylenedioxythiophene) (PEDOT)

Chemical Communications, 2008
Efficient post-functionalization of conductive polymer films was achieved by Cu(+)-catalyzed "click"-cycloaddition of novel poly(azidomethyl-EDOT) and various functionalized terminal alkynes under mild heterogeneous conditions with high conversion efficiencies.

Improved Poly(3,4-Ethylenedioxythiophene) (PEDOT) for Neural Stimulation

Neuromodulation: Technology at the Neural Interface, 2015
This study compares the stability of three variations of the conductive polymer poly(3,4-ethylenedioxythiophene) or PEDOT for neural micro-stimulation under both in vitro and in vivo conditions. We examined PEDOT films deposited with counter-ions tetrafluoroborate (TFB) and poly(styrenesulfonate) (PSS), andPSS combined with carbon nanotubes (CNTs).For ...

Etch-Free Patterning of Poly(3,4-ethylenedioxythiophene)–Poly(styrenesulfonate) for Optoelectronics

ACS Applied Materials & Interfaces, 2015
Spatial control of the conductivity of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is demonstrated through the use of ultraviolet (UV) exposure. With appropriate UV exposure, electrical characterization shows that the in-plane sheet resistance of PEDOT:PSS films is increased by 4 orders of magnitude compared to unexposed regions.

Structure of thin films of poly(3,4-ethylenedioxythiophene)

Synthetic Metals, 1999
Abstract Thin films (50–400 nm) of tosylate-doped poly(3,4-ethylene-dioxy-thiophene) (PEDOT) on various substrates have been studied by grazing incidence X-ray diffraction, using synchrotron radiation. The material was found to be highly anisotropic. This is correlated with a strong anisotropy observed in its optical and electronic properties.

Modified solution technique for preparing poly(3,4‐ethylenedioxythiophene) and a Poly(3,4‐ethylenedioxythiophene)/silver nanocomposite: Optical and thermal behavior

Journal of Applied Polymer Science, 2013
ABSTRACTIn this study, we prepared poly(3,4‐ethylenedioxythiophene) (PEDOT) via the chemical oxidation of the 3,4‐ethylenedioxythiophene monomer in a system consisting of miscible binary organic solvents, that is, acetonitrile (CH3CN) and chloroform (CHCl3). This successful technique was then used to synthesize a poly(3,4‐ethylenedioxythiophene) (PEDOT)

Poly(3,4-ethylenedioxythiophene)/Mesoporous Carbon Composite

The Journal of Physical Chemistry C, 2007
A new type of organic-inorganic poly(3,4-ethylenedioxythiophene) PEDOT/mesoporous carbon composite was first synthesized by a simple in situ polymerization of 3,4-ethylenedioxythiophene monomer within the mesopores and on the particle surface of CMK-3. The composition, morphology, and structure of the composite were investigated by thermal analysis, X ...

Electrochemical Properties of Overoxidized Poly-3,4-Ethylenedioxythiophene

Russian Journal of Electrochemistry, 2018
The properties of poly(3,4-ethylenedioxythiophene) (PEDOT) films were studied electrochemically at high positive potentials (from–0.3 to 1.5 V relative to the Ag/AgCl electrode). A cyclic voltammetry (CV) study revealed the range of potentials (up to 1.3–1.5 V) where the cycling leads to significant changes in the electrochemical, structural, and ...
