“…At present, poly-p-phenylene (PPP), polypyrrole (PPY), polythiophene (PTH), polyphenylacetylene (PPV), and polyaniline (PANI), with enormous monomers, have mostly been studied [19][20][21][22]. Compared with other conductive polymers, PANI attracts much more attentions of researchers due to its simple preparation method, excellent conductivity, and stability [23,24]. In order to increase the multifunctional properties and get improved performances, many scientists have conducted extensive research on conductive polymer/magnetic particle composites, which possess advantages of both the magnetic and the conductive materials [25,26].…”

In this paper, the magnetite/polyaniline (PANI) nanocomposite was prepared by the novel reverse in situ polymerization method. Fe3O4 magnetic nanoparticles were synthesized in situ in PANI chloroform solution to form a suspension containing the Fe3O4/PANI nanocomposite. It overcame the disadvantage of oxidation of the Fe3O4 by the oxidant in conventional method. The Fe3O4/PANI chloroform suspension and the Fe3O4/PANI powder were characterized by FT-IR, TEM, XRD, vibrating sample magnetometer, Gouy magnetic balance, conductivity meter, and vector network analyzer. It is demonstrated that the Fe3O4/PANI suspension has a good electrical conductivity that is up to 2.135 μS/cm at the optimal ratio of reactants. The Fe3O4 nanoparticles are well dispersed in the PANI network with a particle size of about 10 nm. Fe3O4/PANI powder has high saturation magnetization and magnetic susceptibility, as well as a broad application prospect in the field of electromagnetic devices. The Fe3O4/PANI powder exhibits an excellent microwave absorption behavior, which can be an outstanding candidate for the rapid development of broadband shielding materials.

“…Hao et al. 59 first prepared MWCNTs/cotton composites as conductive fabrics and then prepared PANI doped with MWCNTs on conductive fabrics to prepare flexible cotton-based supercapacitor electrodes. The doping of MWCNTs could not only provide good conductivity and a large specific surface area of the electrode but also helped to increase the loading capacity of aniline monomer in PANI polymerization.…”

With the serious impact of fossil fuels on the environment and the rapid development of the global economy, the development of clean and usable energy storage devices has become one of the most important themes of sustainable development in the world today. Supercapacitors, known as ultracapacitors, have been supposed to be one of the most promising candidates to meet the requirements of human sustainable development, due to their advantages such as high capacity, high power density, high charging/discharging speed, long cycle life, and low processing cost. However, the low energy density of supercapacitors limits their large-scale application. Therefore, it is of great significance to develop high energy density supercapacitors and use them as power sources for practical devices. Conductive polymer-based electrode materials have unique advantages such as high theoretical capacitance, good conductivity, and good flexibility, and have high potential in supercapacitors. The research on conductive polymer-based electrode materials has promoted the rapid development of the field of supercapacitors. This review summarizes recent research progress on conductive polymers (including polypyrrole, polyaniline, and polythiophene), conductive polymer-based binary composites, and conductive polymer-based ternary and quaternary composites for supercapacitor electrodes. Furthermore, a summary of the use of conductive polymer-based textiles and fibers for flexible supercapacitors is also presented, along with the current challenges and future perspectives for conductive polymer-based supercapacitors.

“…The development of flexible energy storage devices with a lightweight compact design including high power and high energy density materials are inevitable [2][3][4][5][6][7]. The flexible supercapacitors can be divided into two major types such as electric double-layer capacitors (EDLCs) and pseudocapacitors (PCs) [4,[8][9][10]. The EDLCs store electrical energy through a non-faradaic electrostatic reaction mechanism of charge accumulation at the electrode/ electrolyte interface.…”

“…The EDLCs store electrical energy through a non-faradaic electrostatic reaction mechanism of charge accumulation at the electrode/ electrolyte interface. In general, carbon-based nanomaterials EDLC characteristi exhibit due to a high specific surface area for the reversible charge adsorption or storage with excellent cyclic stability [6,8]. The recent research efforts are extensively devoted to developing conductive-based textiles because of a demand for the huge market potential for wearable smart gadgets [11].…”

The eco-friendly conductive cotton textile is promising alternatives for the flexible substrates in wearable devices since the cotton is as an inexpensive natural fabric material and compatible in modern portable electronics with adequate electrical conductivity. In this work, flexible conductive cotton-based electrodes are prepared via a screen-printing method using the carbonaceous nanomaterials such as carbon nanotubes (CNTs) and graphene with an additional component of conductive silver (Ag) powder and textile ink. The prepared conductive cotton electrodes exhibit lower sheet resistance (<10 Ω) along with superior mass loading (20-30 mg.cm-2). On the basis of the performance of cotton electrodes prepared, an all-solid-state flexible supercapacitor device was successfully fabricated which exhibits a high specific areal capacitance of 677.12 mF.cm-2 at 0.0125 mA.cm-2 for a suitable electrode composition (60% of Ag and 40% CNTs) using a PVA-KOH gel electrolyte. The flexible device endures a stable electrochemical performance under severe mechanical deformation using different bending angles (0°, 30°, 45°, 60° and 90°) of the device and possesses excellent cyclic stability with the capacitance retention of ~80% even after 3000 CV cycles.
