“…PEDOT, poly (3,4-ethylenedioxythiophene) [1][2][3][4], is a conductive polymer [5] that can be used in many different applications such as antistatic coating of polymers and glass, high conductive coatings, organic LED-(OLED) displays [6], nano-fiber electrodes for cell stimulation [7], solar cells, cathode material in electrolytic capacitors, printing wiring boards [8], textile fibres with colour changing properties [9], transparent electrodes for thick-film electroluminescence [10], source gate and drain in the rapidly developing organic semi-conductors field [11].…”

The electronic structure and reflectivity of PEDOT:PSS from density functional theory

et al. 2011

View full text Add to dashboard Cite

The geometric and electronic structure of condensed phase organic conducting polymer PEDOT:PSS blends has been investigated by periodic density functional theory (DFT) calculations with a generalized-gradient approximation (GGA) functional, and a plane wave basis set. The influence of the degree of doping of the PEDOT polymer on structural and optical parameters such as the reflectivity, absorbance, conductivity, dielectric function, refractive index and the energy-loss function is studied. A flip from the benzoid to the quinoid structure is observed in the calculations when the neutral PEDOT is doped by negatively charged PSS. Also the optical properties are affected by the doping. In particular, the reflectivity was found to be very sensitive to the degree of doping, where higher doping implies higher reflectivity. The reflectivity is highly anisotropic, with the dominant contribution stemming from the direction parallel to the PEDOT polymer chain.

“…Poly(3,4-ethylene dioxythiophene) (PEDOT) is one of the best known-conjugated polymers among them, mainly because of its excellent electrical conductivity, and electro-optic properties, metallic behavior, and ease of synthesis [3][4][5][6][7][8][9][10][11][12]. Prepared with standard oxidative chemical, electrochemical, or biomimetic polymerization methods, PEDOT was initially found to be an insoluble polymer.…”

“…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.

“…The junction is covered by a polydimethylsiloxane (PDMS) layer to encapsulate the polymer electrolyte. Electric currents are translated into ionic ones at the patterned PEDOT:PSS electrodes 19 , which in part are covered by aqueous electrolytes, according to the electrochemical reaction PEDOT + :PSS -+ M + (aq) + e -⇔ PEDOT 0 + M + :PSS -. The common-emitter transistor configuration ( Figure 1A) was used throughout this work.…”

Toward Complementary Ionic Circuits: The npn Ion Bipolar Junction Transistor

2011

Many biomolecules are charged and may therefore be transported with ionic currents. As a step toward addressable ionic delivery circuits, we report on the development of a npn ion bipolar junction transistor (npn-IBJT) as an active control element of anionic currents in general, and specifically, demonstrate actively modulated delivery of the neurotransmitter glutamic acid. The functional materials of this transistor are ion exchange layers and conjugated polymers. The npn-IBJT shows stable transistor characteristics over extensive time of operation and ion current switch times below 10 s. Our results promise complementary chemical circuits similar to the electronic equivalence, which has proven invaluable in conventional electronic applications.
