“…For example, the electronic conductivity of poly(3-dodecylthiophene) can approach 1000 S/cm by doping with iodine [3]. Further, doping using polyanions, such as poly(styrene sulfonic acid) (PSS), has been explored to achieve stable, highly conductive and water-processable polymer systems [4,5,6,7], and today such polyelectrolyte-doped conjugated polymer systems are widely used and explored in a wide range of different electronic applications [ 8 ]. During the last decade such material systems have commonly incorporated poly(3,4-ethylenedioxythiophene) (PEDOT) as the electronically conducting phase.…”

Abstract:Poly(3,4-ethylenedioxythiophene) chemically doped with poly(styrene sulfonic acid) (PEDOT:PSS) is a material system commonly used as a conductive and transparent coating in several important electronic applications. The material is also electrochemically active and exhibits electrochromic (EC) properties making it suitable as the active element in EC display applications.In this work uniformly coated PEDOT:PSS layers were used both as the pixel electrode and as the counter electrode in EC display components. The pixel and counter electrodes were separated by a whitish opaque and water-based polyelectrolyte and the thicknesses of the two EC layers were varied independently in order to optimize the color contrast of the display element. A color contrast (ΔE*, CIE L*a*b* color space) exceeding 40 was obtained with maintained relatively short switching time at an operational voltage less than 2 V.

“…Poly(3,4-ethylenedioxythiophene), or PEDOT, possesses excellent properties: ease of synthesis, excellent stability, and wet processability when doped with poly(styrene sulfonic acid) (PSS) [18,19]. Becuase of these properties, PEDOT-PSS or PSS-doped PEDOT are potential candidates as new and unique sensory materials.…”

Abstract:Composites with poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonic acid), PEDOT-PSS, as the matrix containing ZSM-5 zeolites of various Si/Al ratios in the range of 23-280 at 20% (v/v) were fabricated to investigate the effect of Si/Al ratios on electrical conductivity sensitivity responses towards carbon monoxide (CO). The electrical conductivity responses of PEDOT-PSS/ZSM-5 composites were altered due to the available adsorption sites for CO molecules. The electrical conductivity sensitivity to CO increases with decreasing Si/Al ratios. The composites produce irreversible responses when replacing CO with nitrogen. The addition of ZSM-5 zeolites to the pristine PEDOT-PSS improves the electrical conductivity sensitivity of the composites by enhancing the interaction between PEDOT-PSS and CO gas. The composite of ZSM-5 zeolites with a Si/Al ratio equal to 23 gives the highest electrical conductivity sensitivity toward CO.

“…The conductivity of the SE10 film, for example, was as 10 -4 S cm −1 , much lower than 0.1 S cm −1 for the neat PEDOT-PSS film (figure 2). Recent studies have shown that the conductivities of PEDOT-PSS films can be improved by adding a small amount of organic compounds with high boiling points owing to the morphological changes of PEDOT-PSS (relaxation of the polymer chains) induced by the addition of the solvent [20][21][22][23][24][25][26][27]. The conductivities of PEDOT-PSS films containing 5 wt% of additives (DMSO, EG or PEG) were about thousand times higher than that of a PEDOT-PSS film without additives ( figure 2).…”

We have developed a simple method of fabricating transparent conductive films with a high mechanical strength on glass and indium tin oxide substrates. It does not require a large excess of organic solvents and polymerization catalysts and can yield smooth films by spin-coating of a mixture of a commercially available aqueous dispersion of poly(3,4-ethylenedioxythiophene)-poly(4-styrene sulfonate) and a neat liquid of tetraethyl orthosilicate. Preparation conditions such as feed ratio, kinds of additives, and annealing temperature and time were optimized to give highly conductive, transparent and mechanically strong films.
