“…Recently, conductivity of 3400 S/cm was demonstrated for vapor phase polymerized (VPP) poly (3,4-ethylenedioxythiophene):tosylate (PEDOT:Tos) thin films [1] and 7600 S/cm for VPP PEDOT:Cl single-crystal nanowires [2] , rivaling ITO as the material of choice for transparent flexible electrodes. Development of patterning techniques for organic materials is another vein of research receiving a large amount of attention.…”

We demonstrate a novel patterning technique of conductive polymers produced by vapor phase polymerization. The method involves exposing an oxidant film to UV light which changes the local chemical environment of the oxidant and subsequently the polymerization kinetics. This procedure is used to control the conductivity in the conjugated polymer poly(3,4-ethylenedioxythiophene):tosylate (PEDOT:Tos) by more than 6 orders of magnitude in addition to producing high resolution patterns and optical gradients. We investigate the mechanism behind the modulation in the polymerization kinetics by UV light irradiation as well as the properties of the resulting polymer.

Abstract:Conducting polymers (CPs) have been widely studied to realize advanced technologies in various areas such as chemical and biosensors, catalysts, photovoltaic cells, batteries, supercapacitors, and others. In particular, hybridization of CPs with inorganic species has allowed the production of promising functional materials with improved performance in various applications. Consequently, many important studies on CPs have been carried out over the last decade, and numerous researchers remain attracted to CPs from a technological perspective. In this review, we provide a theoretical classification of fabrication techniques and a brief summary of the most recent developments in synthesis methods. We evaluate the efficacy and benefits of these methods for the preparation of pure CP nanomaterials and nanohybrids, presenting the newest trends from around the world with 205 references, most of which are from the last three years. Furthermore, we also evaluate the effects of various factors on the structures and properties of CP nanomaterials, citing a large variety of publications.

“…It was possible to achieve conductivity up to 5400 S/cm by changing the counter ions of PEDOT [12]. Vapor-phase-grown single crystal PEDOT nanowires showed electrical conductivity of 8797 S/cm [13], which is the highest value known for this group of polymers. In spite of this outstanding electrical conductivity, Seebeck coeicient is usually relatively small for polymers.…”

This chapter addresses recent progress in the ield of polymer thermoelectric materials. It covers a brief introduction to intrinsically conductive polymers and its motivation for thermoelectric utilization. A review about important and recent literature in the ield of p-type and n-type polymers for thermoelectric applications is summarized here. For a beter understanding of material development issues, doping mechanisms for intrinsically conducting polymers are discussed. Special emphasis is given to n-type polymers, since this group of polymers is often neglected due to unavailability or poor stability during processing. Diferent possibilities in terms of generator design and fabrication are presented. Recent challenges in this scientiic ield are discussed in respect to current material development, uncertainty during the measurement of thermoelectric properties as well as temperature stability for the most prominent p-type polymer used for thermoelectric, PEDOT:PSS.
