Facile fabrication of polyaniline with coral-like nanostructure as electrode material for supercapacitors

PANI‐chitosan‐TiO2ternary nanocomposite and its effectiveness on antibacterial and antistatic behavior of epoxy coating

“…Polyaniline (PANI) because of its high environmental stability, the facile method of synthesis, and low production expense is almost the most important conducting polymer; and it has commonly been used in sensors, supercapacitors, rechargeable batteries, anticorrosion coatings, and antistatic materials . Generally, antistatic coatings can be classified into two main groups of adding typed and intrinsic typed, the first group is based on conductive additives (i.e., metal powders and carbon derivatives like graphene) and the last one utilizes intrinsic conducting polymers to render the coatings desired conductivity of antistatic materials .…”

Assembly and Interaction of Polyaniline Chains: Impact on Electro- and Physical–Chemical Behavior

“…Recently, Shi et al reported the formation of coral-like PANI and its cyclic voltammogram: it is clear from the cyclic voltammograms that two redox peaks are located very close to each other. The authors explained the shift of the second peak in the negative direction by the presence of Sunset Yellow, which is used as a dopant and surfactant . From our point of view, such electrochemical behavior is related to the fact that PANI chains are assembled in a way where charge propagation is not kinetically and/or diffusionally controlled .…”

“…Electrochemical Properties: Cyclic Voltammetry, Galvanostatic Charge/Discharge and Impedance Spectroscopy. As mentioned above, PANI fibrils have been reported and their electrochemical performance has been studied; 6,7,22 however, the shapes of their cyclic voltammograms described in the literature vary considerably, signaling a subtle influence from the macromolecular arrangements. We proposed that the shapes of cyclic voltammograms depend on the length of the PANI chains and more importantly on the interactions among the PANI chains.…”

“…The authors explained the shift of the second peak in the negative direction by the presence of Sunset Yellow, which is used as a dopant and surfactant. 22 From our point of view, such electrochemical behavior is related to the fact that PANI chains are assembled in a way where charge propagation is not kinetically and/or diffusionally controlled. 1 The PANI nanofibrils synthesized by our group (Figure 1f) possess only one major redox peak situated at 250 mV for anodic and 90 mV for cathodic curves vs Ag/AgCl reference electrode (at a scan rate of 30 mV/s, in the potential window from 0 to 700 mV), which can be seen in the cyclic voltammograms presented in Figure 4b.…”

Impact of dopant ratio on the energy harvesting activity of polyaniline modified counter electrodes for Pt‐free dye‐sensitized solar cells

“…A shoulder at 418-428 nm is ascribed to the polaron to π * transitions indicating incorporation of dopants in polymer backbone. [29,30] The band at infrared region ranging from 790 to 822 nm originates from the charged cationic species, known as π-localized polaron transition. This broadband may be caused by an interband charge transfer from benzenoid to quinoid rings of conjugated PANI.…”
