Production of Conductive PEDOT Nanofibers by the Combination of Electrospinning and Vapor-Phase Polymerization

Abstract

This study reports on the combination of the electrospinning technique and an adapted vapor-phase polymerization procedure to fabricate PEDOT nanofibers. The fibers have average diameters around 350 nm and are soldered at every intersection of the mat, ensuring a superior dimensional stability. The nanofibers are highly ordered at the molecular level, giving the nonwoven mats a very high conductivity (∼60 S/cm), the highest value reported so far for polymer nanofibers. The mats also demonstrate interesting electrochemical properties due to their porous and nanostructured nature. These conductive nanofibers are expected to be of interest for a number of electronic devices requiring flexibility and/or significant surface area, such as sensors or energy storage systems.

Patterning and Conductivity Modulation of Conductive Polymers by UV Light Exposure

“…Films prepared from the oxidant solution displays the typical peaks of both Fe(Tos)3 and triblock copolymer, although it differs from the spectrum of the pure Fe(Tos)3 crystals as previously showed by Laforgue. [17] Films of Clevios CB40 show a broad band at 3115 cm -1 corresponding to H-bonded O-H groups.…”

The electrical properties of PEDOT:PSS nanofibers

“…The first step is the electrospinning of an oxidant solution containing carrier polymer while the second step is polymerization of the EDOT monomer on top of the oxidant nanofibers using a vapor-phase deposition procedure. Unfortunately, the polymerization must be carried out in a vacuum [9].…”

“…Such cylinders can be interpreted as predecessors (i.e. the states before shrinkage) of PEDOT nanofibers, which have been obtained recently (Laforgue and Robitaille, 2010). …”
