Preparation of Conducting Polymer/Metal Nanocomposites

Abstract

This study was primarily focused on the preparation and characterization of conducting polymer=metal nanocomposites. Poly(3,4-ethylenedithiathiophene) was prepared onto ITO electrodes as thin film shapes by electrochemical polymerization and reduced with constant potential. When the polymer films were doped with K 2 PtCl 6 solution, they were easily get oxidized due to the concurrent reduction of Pt(IV) to Pt(0). This procedure ended up with the formation of polymer=metal composites. In-situ spectroelectrochemistry was used to investigate the composite formation processes. The final composites were indentified with SEM and EDAX. Catalytic decomposition of methanol on these composite electrodes was observed by using cyclic voltammetry.

Preparation and characterization of aqueous dispersions of poly(3,4‐ethylenedithiathiophene‐co‐3,4‐ethylenedioxythiophene)/ poly(styrene sulfonate) and their conducting films

“…Poly(3,4‐ethylenedithiathiophene) (PEDTT), as one of the most studied PEDOT analogues, has unique electrical and optical properties and potential applications in the fabrication of rechargeable batteries, sensors, photovoltaic devices, electrochromic devices, polymer‐fullerene devices, and so on 3, 4–23. In the past 20 years, the electrochemical homopolymerization of compounds containing 3,4‐ethylenedithiathiophene (EDTT) units, as listed in Scheme , has been studied in detail 6, 9–11, 16, 18, 20, 22.…”

Effectiveness of alternating mammography and magnetic resonance imaging for screening women with deleterious BRCA mutations at high risk of breast cancer

“…Nowadays, PEDTT and its derivatives have found possible applications as the electron donor materials in photovoltaic devices,35, 37, 38, 41–44 and as the cathode active materials for rechargeable lithium batteries with better cathode capacity than PEDOT 45. More recently, electrosynthesized PEDTT materials were introduced into organic electronic display field and sensors owing to their electrochromic and electrochemical catalytic properties 21, 46–48. However, since firstly reported by Kanitzidis and coworkers in 1995,15 much of the research associated with EDTT has entailed the incorporation of it with other conjugated structures or introduced other functional groups into its structure,16, 17, 35, 37, 38, 41, 42, 46 and most polymers relating to PEDTT were prepared by electrochemical polymerization.…”
