“…The PANI particles form a nanofibrous structure, resulting in a smoother surface than previously reported PAG/PANI. [109][110] In this regard, a quite uniform distribution of PANI-copolymer on the GNS was obtained at GNS-NH 2 weight loadings ranging from 10 to 30 wt%. Higher NH 2 -GNS loadings of ca.…”

“…Furthermore, agglomeration of the PANI particles was also found in some regions of the nanocomposites; the PANI particles that are not nanosized are likely to cause the reduction of the specific capacitance and poor cycling cycles. In this regard, an SC electrode material with smoother morphology and nanosized PANI particles has been demonstrated to deliver enhanced cycling stability and higher specific capacitance, as proven in the recent study by Li et al 109 The combination of PAG/PANI resulted in an SC electrode with a specific capacitance of 1,092.3 F/g under a scan rate of 5 mV/s. 109 This amine group functionalized electrode was constructed by growing the PANI nanoarrays on the PAG.…”

“…The NH 2 -GNS were prepared by using the same previously reported method. 109 The resultant NH 2 -GNS was then mixed with ANI, PPDA, and TPA to synthesize the G-PC nanocomposite. It was shown that incorporating the amine functional group causes an increase in the C and N contents while lowering the O content of Gn; the lower O content can help to reduce the moisture of Gn.…”

The high demand for efficient energy devices leads to the rapid development of energy storage systems with excellent electrochemical properties, such as long life cycles, high cycling stability, and high power density. SC is postulated as a potential candidate to fulfill this demand. The combination of graphene and polyaniline can create SC electrodes with excellent electrical conductivity, high specific surface area, and high capacitance. The graphene/polyaniline hybrid electrodes represent an attractive means to overcome the major drawbacks of graphene or polyaniline non-hybrid (single) electrode materials. In this review article, the trend in the development of various graphene/polyaniline hybrid electrodes is summarized, which includes the zero-dimension graphene-quantum-dots/polyaniline hybrid, one-dimension graphene/polyaniline hybrid, two-dimension graphene/polyaniline hybrid, and three-dimension hydrogel-shaped graphene/polyaniline hybrid. Several strategies and approaches to enhance the capacitance value and cycling stability of graphene/polyaniline hybrid electrodes are discussed in this review article, such as the addition of transition metal oxides and metal-organic frameworks, and modification of graphene into functionalized-graphene. The performance of the electrodes prepared from the combination of graphene with other conducting polymers (i.e., polypyrrole, polythiophene, and polythiophene-derivatives) is also discussed.

“…Due to the PANI's redox transition between leucoemeraldine base states and emeraldine salt, a further transformation from emeraldine to pernigraniline can be suggested [26]. Redox peaks are originated from the faradaic reactions occurring between electrodes' surface and electrolyte ions [27]. The highest capacitance of PGO30 electrode is 13.85 F/g at 5 mV/s.…”

Supercapacitor is an energy device that is applicable in numerous fields because of its excellent reversibility, long life and high power density. Nevertheless, its universal use is restricted by the reduced energy storage capacity and its high crossed series compared to batteries. Even with the relatively high-level output and extensive use of supercapacitor, there is still substantial doubt and ambiguity as to their efficiency in general, especially when it is compared to lithium-ion batteries. The inconsistencies are attributable both to the lack of standardization of the test methods and to the certainty of the strength capacity of the supercapacitor after their resistance has been identified. Therefore, in this work, graphene oxide (GO) and polyaniline (PANI) nanocomposite supercapacitor electrode was fabricated and the performance was investigated by means of cyclic voltammetry and galvanostatic charge-discharge analyses. GO was synthesized using improve Hummers method and PANI using oxidative polymerization chemical synthesis. Three different electrode's compositions were prepared using PANI/GO nanocomposite and labelled as PGO30, PGO50 and PGO70. This article will conclude the electrochemical performance of the electrode.From the results, it was found that PGO50 electrode (50% PANI/50% GO) has the best calculated capacitance with 19.71 F/g compared to the other composite electrodes. This may be attributed from the good electrical conductivity distribution of PANI and graphene oxide. The findings of the work may significantly drive the future of supercapacitor electrode from nanocomposite related materials.

Conjugated polymers have attracted growing attention for versatile applications in energy storage due to their potential benefits including low‐cost processing, molecular tunability, environmental benignity, and high mechanical flexibility. In particular, polymer‐based organic electrode materials have shown significant progress in supercapacitor (SC) applications with superior electrochemical behaviors. The performances of SCs are closely related to the intrinsic characteristics of different polymers in the nanoscale and the morphological features of the polymer‐based electrode materials obtained by different fabrication techniques in the macroscale. This review summarizes the design and synthesis of both p‐type and n‐type conjugated polymers, highlighting the pros and cons of three synthesis techniques: electrochemical polymerization, chemical polymerization, and in situ polymerization. The performances of conjugated polymers in SCs, their cycling stabilities, and structure‐performance relationships are discussed. Moreover, the existing challenges and future directions of polymer‐based SCs are considered with respect to energy density, stability, and large‐scale production to promote commercialization.
