“…The backbone chains of the different PANI electrode material repeatedly move in and out of ions through doping and dedoping 41 . Along with the redox reaction of PANI, polymerization intermediates with positive charges are produced in the reaction process, which can react with nucleophilic groups in electrolyte and solvent, resulting in the gradual degradation of PANI 48 . Compared with the TMCs electrode, the stability performance of the different doped‐PANI electrode is lower in supercapacitors, which was caused by the gradual degradation of PANI itself 49 .…”

Doping transition metal ions into polyaniline (PANI) as an attractive electrode material have been regarded as one of the crucial factors to improve the capacitive performance and the cycle stability of supercapacitors due to their excellent metal properties and good conductivity. Herein, PANI has been prepared via in situ facile and low‐cost electro‐polymerization method. At a current density of 0.2 A g−1, the supercapacitor using PANI electrode shows the specific capacitances of 203.0 F g−1 in 1 M H2SO4 electrolyte. To further improve the electrochemical activity of PANI electrode, the transition metal ions M2+ (M2+ = Ni2+, Co2+, Mn2+, and Cu2+) have been doped into PANI electrode via the same electro‐polymerization method. And the supercapacitor with the different doped‐PANI electrode generates the specific capacitances of 364.3, 326.1, 258.5, and 250.6 F g−1 respectively from PANI‐Ni2+, PANI‐Co2+, PANI‐Mn2+, and PANI‐Cu2+, which were superior to 79.5%, 60.6%,27.3%, and 23.4% of the pristine PANI based counterpart under the same test conditions and method. The favorable performances make the different doped‐PANI act as a new resource of the high performance electrode materials of supercapacitor.

“…While, the third region was a semicircle at higher frequencies, which exhibits the charge transfer resistance between the electrode and electrolyte, which depends on the diffusion of the ions in the electrolyte to the electrode interface. 41 , 42 The radius of the semicircle is directly proportional to the value of charge transfer resistance. 43 The charge transfer resistance of the PANI and PANI@FNCO was 696 and 120 Ω.…”

Conductive polymers have become a remarkable candidate for electrode materials of supercapacitors. Polyaniline (PANI) is the most promising contender for supercapacitors because of its easy method of synthesis, low cost, and higher choice in the improvement of energy storage applications. The main issue in the use of PANI in supercapacitors is its lower stability. In this work, PANI@Fe−Ni codoped Co 3 O 4 (PANI@FNCO) nanocomposite has been prepared by in situ addition of 10 wt % FNCO as fillers in the PANI matrix. The nanocomposites were then characterized via scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry to observe the morphology, crystal structure, functional groups, and thermal stability of samples, respectively. SEM results showed that FNCO was fairly dispersed in the PANI matrix, while XRD results showed a broad peak for nanocomposites because of the semicrystalline nature of polymers. The electrochemical properties of the samples were analyzed via cyclic voltammetry, galvanostatic charge and discharge, and electrochemical impedance spectroscopy. PANI@FNCO nanowires are found to overcome the shortcomings in electrochemical energy storage devices by exhibiting a higher value of specific capacitance of 1171 F g −1 and energy density of 144 W h kg −1 at a current density of 1 A g −1 . Moreover, the FNCO nanowires also showed a cyclic charge/ discharge stability of 84% for 2000 cycles.

structure, which can be easily covalently modified. Progress in extensive organic chemistry of fullerene development facilitates the production of a variety of fullerene derivatives with different structures and physicochemical properties. Additionally, the polyhedral structure of fullerenes containing a large number of bonding sites provides an opportunity for a wide range of covalent modifications. Polymeric structures containing fullerene moieties represent a particularly large class of materials in terms of their number, composition, structure, morphology, and physicochemical properties. [24-29] Some of the most common structures of these polymeric materials are schematically shown in Figure 1. The simplest and most common structures are composites formed from the polymeric chains and fullerenes. Fullerenes form a crystalline phase in the polymeric matrix [30] or are incorporated as guest molecules into polymeric chain containing host moieties. [31] In both cases, covalent interactions are not formed between fullerenes and the polymeric network. However, van der Waals and electrostatic interactions, as well as possible charge transfer between both components of the composite significantly modulate the electronic structure of the polymer/fullerene interphase. [32,33] A stronger electronic interaction between the polymer component and fullerene moieties is expected for the system in which carbon cages are covalently bound to the polymeric chain or covalently incorporated into the polymeric backbone. In the case of in-chain structures, fullerene moieties are separated by short organic conjugated linkers, [34-37] small inorganic linkers, [37-39] or metal atoms and metal complexes. [7,8,29,40-42] A large group of fullerene-based materials consists of organic conducting polymers containing fullerenes attached covalently to the polymer chain by the linker. [43-46] The physicochemical properties of these materials depend on the polymer chain, linker structures, and the density of fullerene moieties within the polymeric material. Similar to olefins, fullerene form homopolymers through [2+2] cycloaddition. [47-51] Fullerene homopolymers, in-chain and side chain fullerene polymers can be cross-linked to form 3D polymeric structures. A large number of reactive π-bond centers in the fullerene moiety enable the formation of star-shaped macromolecular systems with polymeric chains covalently grafted to the C 60. [52-57] In common structures, the number of linked This article provides a comprehensive review of research related to the formation and electrochemical properties of fullerene-based conducting polymeric materials. The paper begins with an overview of composites containing fullerenes incorporated into the network of a conducting polymer through van der Walls, electrostatic, or guest-host interactions. The properties of these composites are generally a superposition of the properties of the individual components. More attention is devoted to the structures in which fullerene is covalently incorporated into the polyme...
