Preparation of sandwich-like ternary hierarchical nanosheets manganese dioxide/polyaniline/reduced graphene oxide as electrode material for supercapacitor

Hierarchical Polyaniline‐MnO2‐Reduced Graphene Oxide Ternary Nanostructures with Whiskers‐Like Polyaniline for Supercapacitor Application

“…The ternary hybrid material rGO/MnO 2 /PANI20 shows poor capacitive performance compared to rGO/MnO 2 /PANI5 and rGO/MnO 2 /PANI10 (in ESI† Figure S5(c‐d)). The best specific capacitance values given by the ternary composite described here are much better than the previous reported values for rGO/MnO 2 /PANI based composite materials in the literature,(ESI†, Table ST1). This result clearly demonstrates that the ordered whisker like structure can enhance the utilization of the electrode material by increasing the electrochemical accessibility of electrolyte through the material.…”

Graphene-based ternary composites for supercapacitors

“…Poly(3,4ethylenedioxythiophene), [35][36][37]31,[38][39][40][41][42][43] and PPy 19,44-48 are commonly CPs used as electrode materials for supercapacitor due to the remarkable electrical conductivity, low cost, flexibility, and ease of preparation. In addition, the combination of these 3 materials can enhance the supercapacitive performance due to the synergistic effect provided by graphene, CP, and metal oxide.…”

“…Both CPs and metal oxides derive their capacitance through redox reactions. Poly(3,4ethylenedioxythiophene), [35][36][37] PANI, 31,[38][39][40][41][42][43] and PPy 19,[44][45][46][47][48] are commonly CPs used as electrode materials for supercapacitor due to the remarkable electrical conductivity, low cost, flexibility, and ease of preparation. 12…”

“…Wu et al 38 have prepared RGO/PANI/MnO 2 via in situ polymerization, in which the RGO surface was coated with PANI to form RGO/PANI followed by mixing the PANI/RGO hybrid nanosheets with KMnO 4 to form RGO/PANI/MnO 2 . The synergistic effect of the combination of the 3 materials has been proved to enhance the electrochemical performance of the RGO/PANI/MnO 2 with the maximum specific capacitance obtained of 1090.2 F/g at 0.5 A/g in 1 M KOH.…”

Electrochemical Pseudocapacitors Based on Ternary Nanocomposite of Conductive Polymer/Graphene/Metal Oxide: An Introduction and Review to it in Recent Studies

“…[23] The third one is a hybrid capacitor, prepared through combining both EDLC and pseudocapacitor. [10] The ternary composites composing of carbon materials, metal oxides, and conductive polymers, e. g. poly(3,4-ethylene-dioxythiophene) (PEDOT)/graphene/SnO 2 , [24] reduced graphene oxide/polyaniline (PANI)/MnO 2 , [25] polypyrrole (PPy)/TiO 2/ graphene, [26] and SnO 2 /reduced graphene oxide/polyaniline, [27] 908 -926 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 have been significantly studied in recent years to solve the above-mentioned drawbacks. [28][29][30] They utilize both Faradaic and non-Faradaic procedures to store charge, leading to higher specific capacitance and energy density, high cell voltage, longer life cycle and moderated power density.…”
