“…A higher specific capacitance was successfully obtained by GO/PEDOT/lCNT (95.2 mF/cm 2 ) compared with GO/PEDOT/sCNT (86.1 mF/cm 2 ) at 10 mV/s. According to Hao et al, 71 GO provides an adequate specific surface area for GO/multiwalled CNTs (MWCNTs)/PANI ternary composite as PANI has low specific surface area. The symmetric supercapacitor of the GO/PEDOT/lCNT was assembled and separated by PVA/phosphoric acid polymer gel electrolyte and exhibited maximum specific energy and specific power of 4.4 μWh/cm 2 and 4.0 mW/cm 2 , respectively.…”

“…In addition, the ternary composite exhibited specific energy and specific power of 19.6 Wh/kg of and 2.2 kW/kg, respectively, at a current density of 4 A/g. According to Hao et al, 71 GO provides an adequate specific surface area for GO/multiwalled CNTs (MWCNTs)/PANI ternary composite as PANI has low specific surface area. The specific surface area is crucial to maximizing the diffusion of ions into the active materials for charge storage.…”

Summary The research on electrode materials for supercapacitor application continues to evolve as the request of high‐energy storage system has increased globally due to the demand for energy consumption. Over the past decades, various types of carbon‐based materials have been employed as electrode materials for high‐performance supercapacitor application. Among them, graphene is 1 of the most widely used carbon‐based materials due to its excellent properties including high surface area and excellent conductivity. To exploit more of its interesting properties, graphene is tailored to produce graphene oxide and reduced graphene oxide to improve the dispersibility in water and easy to be incorporated with other materials to form binary composites or even ternary composites. Nowadays, ternary composites have attracted enormous interest as 2 materials (binary composites) cannot satisfy the requirement of the high‐performance supercapacitor. Thus, many approaches have been employed to fabricate ternary composites by combining 3 different types of electroactive materials for high‐performance supercapacitor application. This review focuses on the supercapacitive performance of graphene‐based ternary composites with different types of active materials, ie, conducting polymers, metal oxide, and other carbon‐based materials.

Polyaniline has been widely used in high-performance pseudocapacitors, due to its low cost, easy synthesis, and high theoretical specific capacitance. However, the poor mechanical properties of polyaniline restrict its further development. Compared with polyaniline, functionalized carbon materials have excellent physical and chemical properties, such as porous structures, excellent specific surface area, good conductivity, and accessibility to active sites. However, it should not be neglected that the specific capacity of carbon materials is usually unsatisfactory. There is an effective strategy to combine carbon materials with polyaniline by a hybridization approach to achieve a positive synergistic effect. After that, the energy storage performance of carbon/polyaniline hybridization material has been significantly improved, making it a promising and important electrode material for supercapacitors. To date, significant progress has been made in the synthesis of various carbon/polyaniline binary composite electrode materials. In this review, the corresponding properties and applications of polyaniline and carbon hybrid materials in the energy storage field are briefly reviewed. According to the classification of different types of functionalized carbon materials, this article focuses on the recent progress in carbon/polyaniline hybrid materials, and further analyzes their corresponding properties to provide guidance for the design, synthesis, and component optimization for high-performance supercapacitors.

“…Nowadays, ternary composites combining polymers with two types of carbonaceous nanomaterials of different structures and properties are of special interest. Despite the similarities of composites prepared from the same components, many of the described materials exhibit considerable differences in microstructure, physicochemical and electrochemical behaviour [29][30][31][32][33][34][35]. For instance, Mahakul et al [31] investigated the ternary composites consisted of PEDOT-poly(sodium4-styrenesulfonate) (PSS), reduced graphene oxide (rGOx) and oxidised carbon nanotubes (oxMWCNTs) prepared by the simple mixing of PEDOT/PSS solution with rGOx and different amount of oxMWCNTs.…”

“…On the other hand, Chen et al [33] prepared PEDOT hollow spheres (b-PEDOT) with graphene oxide and oxidised multiwalled carbon nanotubes (b-PEDOT/GOx/MWCNTs) composite which showed a maximum capacitance of 225 F g −1 at 0.1 A g −1 during galvanostatic charge/discharge in the two-electrode system with 5 M KOH serving as the electrolyte. Kim et al [34], Shen et al [33] and Hao et al [35] investigated electrochemical performance of the ternary composites consisting of polyaniline, modified graphene oxide and oxidised multiwalled carbon nanotubes in 1 M H 2 SO 4 aqueous composite. Despite comprising of the same components, the composites exhibit different capacitance values measured in a three-electrode system in contact with 1 M H 2 SO 4 electrolyte, namely 440 F g −1 (at 1 A g −1 ) [34], 495 F g −1 (at 1 A g −1 ) [36] and 696 F g −1 (at 20 mV s −1 ) [35].…”

This paper reports on the role of oxidised carbon nanotubes (oxMWCNTs) present in poly-3,4-ethylenedioxytiophene (PEDOT)/graphene oxide (GOx) composite. The final ternary composites (pEDOT/GOx/oxMWCNTs) are synthesised by an electrodeposition process from the suspension-containing monomer, oxidised carbon nanotubes and graphene oxide. Dissociated functional groups on the surface of graphene oxide play a role of counter-ions for the polymer chains. Detailed physicochemical and electrochemical characterisation of the ternary composites is presented in the paper. The results prove that the presence of oxMWCNTs in the ternary composites doubles the capacitance values compared to the binary ones (450 vs. 270 F cm−3 for PEDOT/GOx/oxMWCNTs and PEDOT/GOx, respectively). The amount of carbon nanotubes in the synthesis solution is crucial for physicochemical properties of the composites, their adhesion to the electrode substrate and the electrochemical performance.
