Self-doped conducting copolymers: a charge and mass transport study of poly{pyrrole-CO[3-(pyrrol-1-YL)propanesulfonate]}

Electropolymerization of cyclodextrin/4-aminobiphenyl inclusion complex generating water-soluble pseudo-oligorotaxanes in their oxidized state

“…This oxidation takes place outside the CD cavity [19] and leads to the formation of pseudopolyrotaxanes deposited on the electrode surface, with irreversible incorporation of CD during the film reduction in cyclic voltammetry. CD incorporation was studied by quartz microbalance measurements (EQCM), which is a convenient technique for following matter electrodeposition [20][21][22][23]. Similar experiments with other hydrophobic monomers electropolymerized in aqueous media [24][25][26][27] did not give pseudopolyrotaxanes and led only to polymer formation.…”

Interpretation of the ultra-fast electropolymerization of pyrrole in aqueous media on zinc in a one-step process: The specific role of the salicylate salt investigated by X-ray photoelectron spectroscopy (XPS) and by electrochemical quartz crystal microbalance (EQCM)

“…An iron oxalate layer is formed first but, in contrast to salicylate (ex situ XPS results), this layer is desorbed prior to pyrrole oxidation. The use of EQCM to monitor mass changes at the electrode surface during electrochemical reactions or during electrochemical growth of conducting polymers has been reported previously [45,46]. EQCM is a sensitive enough technique to determine the mass of adsorbed species on various substrates, and in this case it was employed to study the passivation of a zinc surface and the growth of polypyrrole on it during cyclic voltammetry (CV).…”

Electropolymerized Films of π‐Conjugated Polymers. A Tool for Surface Functionalization: A Brief Historical Evolution and Recent Trends

“…When the anionic dopant is immobilized, the dedoping results in the insertion of a cation to insure the electroneutrality [135] ( Figure 1.2c). This cationic pseudodoping is also performed when the anionic dopant, usually sulfonate, is directly grafted on the conjugated polymer skeleton (self-doped polymers [136][137][138][139][140][141][142]) or is a pending group of an ionomeric polymer such as Nafion  [136,143,144] or polystyrene sulfonate [145,146]. Such interpenetrated polymeric networks [70] were investigated for applications in batteries [71,117], water deionization [71,117], and electrochemical delivery of drugs [118][119][120].…”
