“…Recently, conducting polymer materials have been studied widely in many fields because of their low density, good thermal and chemical stability, reproducibility, and controllable conductivity [ 11 , 12 , 13 ]. Polyaniline (PANI), which is one of the most promising and extensively investigated conducting polymers, has been applied extensively to several areas, such as supercapacitors [ 14 ], catalysts [ 15 ], sensors [ 16 ], and biological fields [ 17 ], because of its electro-activity, environmental and chemical stability, controllable conductivity, biological compatibility, ease of preparation, and low cost [ 18 ]. Furthermore, the properties of ER fluids based on different forms of PANI synthesized by different methods have been studied extensively [ 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”

Functional core-shell-structured particles have attracted considerable attention recently. This paper reviews the synthetic methods and morphologies of various electro-stimuli responsive polyaniline (PANI)-coated core-shell-type microspheres, including PANI-coated Fe 3 O 4 , SiO 2 , Fe 2 O 3 , TiO 2 , poly(methyl methacrylate), poly(glycidyl methacrylate), and polystyrene along with their electrorheological (ER) characteristics when prepared by dispersing these particles in an insulating medium. In addition to the various rheological characteristics and their analysis, such as shear stress and yield stress of their ER fluids, this paper summarizes some of the mechanisms proposed for ER fluids to further understand the responses of ER fluids to an externally applied electric field.

“…The preparation of conductive hydrogels that are based on PANI has shown tremendous attraction towards different applications such as water treatment [ 69 ], supercapacitors [ 126 ], and bone tissue engineering [ 7 ]. Bagheri et.al [ 69 ] first prepared hydrogel by the polymerization of acrylic acid in the presence of carboxymethyl cellulose (CMC), a small amount of a cross-linker, and ammonium persulfate (APS) as an initiator ( Figure 10 ).…”

Electrically conductive materials that are fabricated based on natural polymers have seen significant interest in numerous applications, especially when advanced properties such as self-healing are introduced. In this article review, the hydrogels that are based on natural polymers containing electrically conductive medium were covered, while both irreversible and reversible cross-links are presented. Among the conductive media, a special focus was put on conductive polymers, such as polyaniline, polypyrrole, polyacetylene, and polythiophenes, which can be potentially synthesized from renewable resources. Preparation methods of the conductive irreversible hydrogels that are based on these conductive polymers were reported observing their electrical conductivity values by Siemens per centimeter (S/cm). Additionally, the self-healing systems that were already applied or applicable in electrically conductive hydrogels that are based on natural polymers were presented and classified based on non-covalent or covalent cross-links. The real-time healing, mechanical stability, and electrically conductive values were highlighted.

“…In the gel-based electrolyte, the solvent was evaporated during the gel preparation process, so electrolyte decomposition due to water was prevented. In the CMC/KOH gel electrolyte, solvated ions were surrounded by a complex CMC matrix; that matrix enhanced the electrode/electrolyte interactions through strong attachment of the electrolyte to the electrode material [33][34][35]. Moreover, the current collector was coated with a thin layer of carbon, so the oxidation of the Ni current collector was inhibited.…”

“…Aqueous, nonaqueous, solid-state, inorganic, dry solid polymer, and redox-active gel polymer electrolyte have all been employed in HSC development. From the above electrolyte types, carboxymethyl cellulose and KOH (CMC/KOH)-based gel electrolyte show high accessible potential windows, amended attachment with electrode material, nontoxicity, high dielectric constants, and high thermal and chemical stability [30][31][32][33][34][35]. Furthermore, various kinds of current collectors have used in the development of HSCs, including Ni foam, Al foil, carbon cloth, Ni foil, and stainless-steel mesh.…”

In Situ Binder-Free and Hydrothermal Growth of Nanostructured NiCo2S4/Ni Electrodes for Solid-State Hybrid Supercapacitors

Herein, we report a comparison of the electrochemical performance of two kinds of NiCo2S4-based electrodes for solid-state hybrid supercapacitors (HSCs). For the binder-free electrode, NiCo2S4 was grown on Ni foam by the chemical bath deposition (CBD) method. For the binder-using electrode, NiCo2S4 powder was synthesized by the hydrothermal method. FESEM images depicted the hierarchical nanostructure of NiCo2S4 synthesized by the hydrothermal method and uniform distribution of nanostructured NiCo2S4 grown on Ni foam by the CBD method. Half-cell studies of both NiCo2S4 electrodes showed them exhibiting battery-type charge storage behavior. To assemble HSCs, NiCo2S4 and activated carbon were used as a positive and negative electrode, respectively. Electrochemical studies of the HSCs showed that the accessible potential window was wide, up to 2.6 V, through cyclic voltammetry (CV) analysis. Chronopotentiometry (CP) studies revealed that the energy and power densities of binder-using HSC were 51.24 Wh/kg and 13 kW/kg at 1 Ag−1, respectively, which were relatively higher than those of the binder-free HSC. The binder-free HSC showed 52% cyclic stability, relatively higher than that of the binder-using HSC. Both HSCs, with unique benefits and burdens on energy storage performance, are discussed in this work.
