Conducting polyfurans by electropolymerization of oligofurans

Abstract

Polyfuran films produced by electropolymerization of a series of oligofurans substituted with alkyl groups show improved properties, such as good conductivity and stability, well-defined spectroelectrochemistry and smooth morphology.

Analysis of Conjugated Polymers Conductivity by in situ Electrochemical‐Conductance Method

“…Another alternative is the use of a bipotentiostat (4) to keep the constant potential between the combs of the IDME (Figure b). The first channel of the bipotentiostat is used in the standard three electrode mode, while the second channel is used to apply the Δ V between the both parts of the IDME . In‐situ conductivity measurements of several conducting polymers by means of the bipotentiostat mode has been obtained .…”

“…In recent years using this technique, different polymer films derived from polyfurans, PTh, PPy, PANI, polyalcoxythiophenes to organometallics polymers, dendrimer structures and conjugated radical polymers, have been examined. [81,[92][93][94][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109][110] Conductance behavior, charge/discharge process, n-doping and charge trapping are the most common phenomena studied. Commonly these studies have been carried out using low scan rate values (v � 10 mV s À 1 ) in order to obtain reliable data, because some structural changes during the charge/discharge process are slow and using higher scan rates unreproducible data could be obtained.…”
