“…Recently, Kumar et al [149] demonstrated that a specific capacitance of 395 F/g could be achieved in p-tolune-sulfonate (pTS)-doped PPy/C composites in Na 2 SO 4 aqueous solution. For direct growth of PPy on the current collector, the electropolymerization process is mostly used for supercapacitor application [150,151]. In 2012, Dubal et al [152] have demonstrated various nanostructures of PPy on stainless steel via electropolymerization method for ES application, as shown in Figure 9.…”

Flexible supercapacitors, a state-of-the-art material, have emerged with the potential to enable major advances in for cutting-edge electronic applications. Flexible supercapacitors are governed by the fundamentals standard for the conventional capacitors but provide high flexibility, high charge storage and low resistance of electro active materials to achieve high capacitance performance. Conducting polymers (CPs) are among the most potential pseudocapacitor materials for the foundation of flexible supercapacitors, motivating the existing energy storage devices toward the future advanced flexible electronic applications due to their high redox active-specific capacitance and inherent elastic polymeric nature. This review focuses on different types of CPs-based supercapacitor, the relevant fabrication methods and designing concepts. It describes recent developments and remaining challenges in this field, and its impact on the future direction of flexible supercapacitor materials and relevant device fabrications.

“…This means that the results of both experiments consist of the impedance and cyclic voltammetry tests confirm each other. As shown in the diagram, both electrodes have Warburg (ZW) resistance impedance in the low-frequency region, is a result of the dependence of the ion emission/transfer frequency from an electrolyte to the electrode surface [25]. The Nyquist design data is placed in an equivalent circuit, shown in Figure 8, indicating the a bulk solution resistance Rs, a charge-transfer resistance R ct, a constant phase element for simulating the doublelayer capacitance (Cdl), and a Warburg (ZW) resistance impedance.…”

Considering the importance of conductive polymer nanocomposite, the present paper attempts to create a method for increasing the conductivity of poly(o-aminophenol). Nanocomposite MnO 2 /poly(o-aminophenol) thin film was synthesized by using pulse potential electrodeposition technique on a graphite electrode. In this research, nanoparticles of MnO 2 are used after synthesis to prepare polymer nanocomposites in one-step. Appending of MnO 2 to polymer matrix increases the current. This current growth could be ascribed to the synergistic MnO 2 nanostructure, which presents the superior surface area and smaller particle size that is increasingly acting sites. Morphology or samples composition was investigated by the scanning electron microscope and the UV-Vis method, which clearly indicate the formation of nanocomposites. The findings show that the capacitive behavior of MnO 2poly(o-aminophenol) is superior to poly(o-aminophenol), especially at high potential high temperatures. The results showed that MnO 2 /poly(o-aminophenol) had a higher level of activity and the electron transfer capability was faster than pure polymer film. The doped MnO 2 polymer also has excellent cyclic performance and load discharge features. Additional electrochemical properties of these polymer composites were observed against pure polymer so that capacity of 645 Fg −1 has been designated.

“…Conductive polymers can be synthesized chemically and electrochemically. Electrochemical synthesis can be realized on electrodes such as platin, copper, aluminum, and steel by either galvanostatic or potentiostatic or potentiodynamic technique. Electrochemical synthesis is quick and easy to control.…”

film was synthesized in 0.30 M oxalic acid solutions containing 0.05 M aniline + 0.05 M pyrrole + 0.05 M N-methylpyrrole. Poly(aniline-co-pyrrole-co-N-methylpyrrole)-TiO 2 nanocomposites were synthesized in 0.30 M oxalic acid solutions containing 0.05 M aniline + 0.05 M pyrrole + 0.05 M N-methylpyrrole + 0.1/0.4/1.0 gL À 1 TiO 2 .Electrochemical syntheses were performed on the carbon steel (CS) elctrode using cyclic voltammetry technique. The terpolymer and nanocomposites were characterized by SEM, EDX, electrochemical impedance spectroscopy (EIS), open circuit potential-time and anodic polarization techniques. Nanocomposite structures were observed after the addition of TiO 2 nanoparticles into terpol-ymer films and these results was verified via EDX analysis. The results driven by EIS and anodic polarization suggest that, terpolymer and nanocomposite coated electrodes have been shown to have a protective effect against the corrosion of the CS electrode. The nanocomposite coated electrode synthesized in an environment containing 0.4 gL À 1 TiO 2 was found to have higher corrosion resistance in comparison to uncoated electrode, terpolymer coated electrode and electrodes coated with nanocomposites that is synthesized in environments containing 0.1/1.0 gL À 1 TiO 2 . These results showed that the amount of TiO 2 affects the anticorrosive properties of the synthesized nanocomposite.
