Raman spectroelectrochemical study on the kinetics of electrochemical degradation of polyaniline

Effects of Tritium Gas Exposure on Electrically Conducting Polymers

“…The observed intensity losses at the higher doses for both Raman and absorbance spectroscopy echo the results reported by Mažeikienė et al [Mažeikienė , 2008]. These authors used in-situ Raman spectroscopy to monitor the effects of electrochemical treatment of a polyaniline film deposited on a gold electrode.…”

Structural changes in polyaniline near the middle oxidation peak studied by in situ Raman spectroelectrochemistry

“…Three oxidation peaks are detected by cyclic voltammetry of PANI; ‘first’ peak belongs to the oxidation from leucoemeraldine to emeraldine and the ‘second’ to the transition from emeraldine to pernigraniline and chain growth . The current of the ‘middle’ peak is typically observed in early stages of PANI film growth, decreases with film thickness, and increases again with oxidative degradation . It was attributed to the oxidation of the products of hydrolysis and hydroquinones or to the phenazine‐like cross‐linked structures …”

“…[4,5] The current of the 'middle' peak is typically observed in early stages of PANI film growth, decreases with film thickness, [7] and increases again with oxidative degradation. [8,9] It was attributed to the oxidation of the products of hydrolysis and hydroquinones [6,7,[10][11][12] or to the phenazine-like cross-linked structures. [13] However, the doping of PANI is not fully described by these three redox processes.…”

Electrochemistry of new generation conformal polyaniline/carbon scaffolds with monodispersed nanopores and high capacitance

“…Overall, the Raman spectra of the PANI/NCS-85 composites are very similar to the Raman spectra reported earlier for other PANI systems. 46,47 As seen in Fig. 2d, the two broad peaks in the Raman spectrum of the NCS-85 at ca.…”
