PEDOT as an Electrode Material for Solid Electrolyte Capacitors

PEDOT film that after rinsing with water and n-butanol exhibits conductivities of up to 550 S/cm.  

Another polymerization method for EDOT is the so-called BAYTRON P synthesis, which was developed at Bayer AG and modified by ELECON, Inc. This method utilizes the polymerization of EDOT in an aqueous polyelectrolyte (most common polystyrene sulfonic acid [PSS]) solution using Na2S20g as the oxidizing agent. 

The reaction at room temperature results in a dark-blue, aqueous PEDOT/PSS dispersion, which is commercially available from Bayer AG under the trade name BAYTRON P and from ELECON under the trade name ELEFLEX13 2000. After dr5dng of BAYTRON P and ELEFLEX 2000, the remaining PEDOT/PSS film is highly conducting, transparent, mechanically durable, and insoluble in any common solvent. 

The structural model for tosylate-doped PEDOT presented a contribution to the structural characterization of PEDOT by using de Leeuw s chemical method extended to a surface-confined polymerization. Thin PEDOT films were formed that were subsequently studied with grazing incidence X-ray diffraction using synchrotron radiation. From these studies it was concluded that the material is very anisotropic and these thin films exhibit a limited crystalline order. 

PEDOTs electronic structure by X-ray and ultraviolet photoelectron spectroscopy was also studied as well as by spectroscopic ellipsometiy. These results suggest that PEDOT prepared in this manner can be seen as an anisotropic metal.
