Preparation of PEDOT/Cu composite film by in situ redox reaction between EDOT and copper(II) chloride

A facile solid-state heating method for preparation of poly(3,4-ethelenedioxythiophene)/ZnO nanocomposite and photocatalytic activity

“…In recent years, there has been an increasing interest in the development of polymer/inorganic nanohybrid materials [ 1 - 3 ]. Inorganic semiconductors such as ZnO, TiO 2 , MnO 2 , and ZrO 2 have been extensively investigated as hybrids with polymers having synergetic or complementary properties and behavior for the fabrication of a variety of devices.…”

The structure and electrochemical properties of poly(3,4-propylenedioxythiophene)/SnO2nanocomposites synthesized by mechanochemical route

“…According to the previous reports, the synthesized polymers are in partially doped state during the FeCl 3 oxidative polymerization of polythiophene, and the FeCl 4 2 ion is the most probably the counter anion for the FeCl 3 doped polymer [41]. Furthermore, all nanocomposites from both methods also displayed rather broad peak at 2u 5 24 , revealing small degree of crystallinity but amorphous structure of PPro-DOT, and it is similar to some other polythiophene derivatives [46][47][48].…”

Vapor phase polymerization and mechanical testing of highly electrically conductive poly(3,4-ethylenedioxythiophene) for flexible devices

“…The spectra shows a broad peak above 900 nm in the Fe(PTS) 3 /PEDOT and PEDOT:PSS samples. This is a result of a bipolaron state which indicates anion doping and an extended polymer chain conformation [22,32]. VPP PEDOT using CuCl 2 does not show an apparent broad peak in the near IR region which is indicative of a lower doping content, leading to a lower conductivity.…”

“…The conductive nature of VPP PEDOT thin films varies depending on factors like choice of oxidant, vapor pressure, and environmental conditions, such as temperature, which can alter the conductivity by a factor of 3 or more [20][21][22]. When using the oxidant Fe(III) p-toluenesulfonate hexahydrate (Fe(PTS) 3 ) as the initiator, the VPP method has been shown to produce highly conductive films, with conductivities greater than 1000 S/cm [23,24].…”

“…The high conductivities have been attributed to the dopant anion which induces a postive charge on the polymer and increases the overall order and crystallinity of the film compared to solution processing methods [25]. PEDOT polymerization has also been done utilizing different oxidants, such as Cu(II) chloride, though the obtained conductivities are lower [22].…”
