PEDOT vapor-phase polymerization

Vapor-phase polymerization has been used to create a PEDOT structure into which even delicate biomolecules such as enzymes can be incorporated during the subsequent washing step.37... 

Futhermore, nanofiber scaffold electrodes based on PEDOT for cell stimulation were recently reported by Bolin et al. [87]. Electronically conductive and electrochemically active three-dimensional scaffolds based on electrospun poly(ethylene terephthalate) (PET) nanofibers were prepared. Vapor-phase polymerization was employed to achieve a uniform and conformal coating of poly(3,4-ethylenedioxythiophene) doped with tosylate (PEDOT tosylate) on the nanofibers. The PEDOT coatings had a large impact on the... 

Laforgue et al. reported on a combination of electrospinning and vapor-phase polymerization to fabricate PEDOT nanofibers [60]. Figure 7 shows the optical microscope and SEM images of these electrospun PEDOT nanofibers. Their average diameter was 350 ( 60) nm.

Flexible supercapacitors were made from PEDOT nanolibers as electrodes and polyacrylonitrile (PAN) nanolibers as separator by Larfogue et al. [19]. The PEDOT nanolibers were produced by combination of electrospinning and vapor-phase polymerization to form a conductive mat, and were used as the active material (electrodes), separated by a sheet of PAN nanolibers. Carbon-based clothes were used as the current collectors. The material layers were stacked together and embedded in a solid electrolyte containing an ionic liquid and polyvinylidene lluoride-co-hexa-fluoro-propylene (PVDF-co-HFP) as the host polymer. 

Beginning with first attempts by J. Kim et al., a new route to highly conductive PEDOT layers by vapor phase polymerization (VPP) was been established in 2003 to 2005. - Substrates coated with iron(III)-tosylate as the oxidant were deposited in a polymerization chamber, where the evaporation of EDOT and its polymerization on the substrate was performed by bubbling different gases (air, nitrogen, argon) through the EDOT reservoir. 

Bradley s group of at Imperial College London investigated the vapor phase polymerization of EDOT on to iron(lll)-tosylate coated glass or plastic substrates. A very high conductivity of about 1200 S/cm was reported, one of the highest values ever found for PEDOT.
