Facile Synthesis of Poly(3,4‐ethylenedioxythiophene) Nanofibers from an Aqueous Surfactant Solution

Abstract

Easy does it: Poly(3,4‐ethylenedioxythiophene) (PEDOT) fibers can be synthesized from aqueous solutions of anionic surfactant by a self‐assembly method. This approach readily generates nanofibers with diameters down to about 10 nm and lengths of over 5 μm (see TEM image). The fibers can be produced with high yields and exhibit electrical conductivities of approximately 46 S cm−1.

Synthesis of Cobalt Ion‐Based Coordination Polymer Nanowires and Their Conversion into Porous Co3O4 Nanowires with Good Lithium Storage Properties

“…Some ligands can result in the formation of vesicles, micelles and coordination inorganic-organic nanomaterials with different morphologies in solution via coordination with metal ions. [25][26][27] These nanostructures are often used as precursors of metal oxide or soft templates of other nanomaterials. [28][29][30][31][32] From a fundamental viewpoint, it is highly desirable to understand the mechanism between metal ions and ligands because of their potential applications in the detection of metal ions, water treatment and drug delivery.…”

Electrical conduction mechanism of poly(3,4-ethylenedioxythiophene) nanofiber bundles at low temperature

“…The diffraction peaks centered around 6.7°, 18.8°and 25.3°c orrespond to the (100), (300) and (400) planes of PEDOT, respectively [18]. The intense diffraction peak centered at 25.3°is attributed to the interchain planar ring-stacking distance [14]. It is observed that the sharpness of diffraction peaks increases with increasing SDS concentration, which is indicative of an increased periodicity of polymer chains.…”

“…One of the most salient features of EDOT is that the substitution at the 3-and 4-positions of thiophene ring prevents the occurrence of a-b and b-b coupling during polymerization, which results in more ordered polymer chains with longer conjugation lengths [13]. Han and Foulger [14] have reported the synthesis of PEDOT nanofibers by using SDS as surfactant; however, the effect of varying concentration of SDS on the electrical transport properties has not been systematically investigated. The electrical transport and magnetoresistance properties of PEDOT have been reported by different groups, Sangeeth et al [15], de Oliveira et al [16] and Aleshin et al [17]; however, the mechanism and the effect of disorder on these properties are not fully understood.…”

Chemical synthesis of PEDOT/Ag nanocomposites via emulsion technique in silver colloid

“…In both spectra, the absorption maximum located at about 600 nm is the characteristic of PEDOT, which is associated to the π→π* transition. [33,34] For the pure PEDOT prepared through a conventional emulsion technique, this broad band centered around 563 nm. For PEDOT/Ag nanocomposite, however, a slight red shift was observed.…”
