“…The characteristic peak of CCDPC exists at 21.5°, corresponding to the plane (002) of the carbon material, which means the amorphous structure of CCDPC . Compared with the original CCDPC, the XRD pattern for CCDPC/PANI composite material has an obvious diffraction peak of PANI located at 25.1° (200), and a slight characteristic peak at 20.4° (020), manifesting that PANI particles are successfully covered on the surface of CCDPC . In addition, the XRD spectra of CCDPC and CCDPC/PANI show diffraction peaks around 33–35°, which probably originated from the inherent tiny silicate impurity in CaC 2 .…”

A solvent-free mechanochemical method is a green and environmentally friendly preparation technology for the preparation of calcium carbide-derived porous carbon (CCDPC). Although CCDPC can be widely used in the fields of energy storage, gas separation, catalysis, and so on, the performance of CCDPC as an electrode material of supercapacitors still needs to be further improved. Based on the in situ chemical oxidation polymerization method, in this paper, polyaniline (PANI) is successfully introduced into CCDPC and covered on the surface and skeleton of CCDPC. It has been found that the as-prepared CCDPC/PANI composite electrode displays a high specific capacitance of 362 F g–1 at 0.5 A g–1, which is approximately 4 times higher than that of the pure CCDPC electrode. When assembling a symmetric supercapacitor by a CCDPC/PANI composite with a wide voltage window of 0–1.1 V, the supercapacitor delivers a higher energy density than CCDPC and reveals excellent capacitance retention of 77% after 10,000 cycles. Therefore, the preparation technology of the CCDPC/PANI composite provides significative exploration for the enhancement of electrochemical performance of high-performance supercapacitors and predicts a promising application prospect in the field of energy storage.

“…The morphology and porous structure of the electrode have a more significant impact on the electrochemical performance at higher rates. The gravimetric specific capacitance of the as-obtained CNF-PAA/PPy electrodes was found to be higher than that of other porous hydrogel electrodes with PPy reported in the literature, such as crosslinked PAAm filled with carboxymethylcellulose (CMC)/PPy (~140 F/g at 0.5 A/g) [73], a carboxylated CNF/PPy film electrode (~180 F/g at 0.5 A/g) [74], a CMC-PANI/carbon nanotube film electrode (348.8 F/g at 0.5 A/g) [75], and a porous, pure polypyrrole hydrogel prepared via the ice-templating method (265 F/g at 1.35 A/g) [76]. This comparison demonstrates the possible practical interest in electrodes based on colloid brushes.…”

This feature article is devoted to the evaluation of different techniques for producing colloidal polyelectrolyte brushes (CPEBs) based on cellulose nanofibers modified with grafted polyacrylates. The paper also reviews the potential applications of these CPEBs in designing electrode materials and as reinforcing additives. Additionally, we discuss our own perspectives on investigating composites with CPEBs. Herein, polyacrylic acid (PAA) was grafted onto the surface of cellulose nanofibers (CNFs) employing a “grafting from” approach. The effect of the PAA shell on the morphological structure of a composite with polypyrrole (PPy) was investigated. The performance of as-obtained CNF-PAA/PPy as organic electrode material for supercapacitors was examined. Furthermore, this research highlights the ability of CNF-PAA filler to act as an additional crosslinker forming a physical sub-network due to the hydrogen bond interaction inside chemically crosslinked polyacrylamide (PAAm) hydrogels. The enhancement of the mechanical properties of the material with a concomitant decrease in its swelling ratio compared to a pristine PAAm hydrogel was observed. The findings were compared with the recent theoretical foundation pertaining to other similar materials.

“…The paper demonstrated the SC of 880 F/g at a current density of 1.5 A/g, an energy density of 68.4 mWh/g, a power density of 895.4 mW/g, and 80.6% CR after 10,000 cycles. Xu et al [106] demonstrated a flexible, symmetric supercapacitor based on the CNT/PANI-Carboxymethylcellulose (CMC) electrode with a gravimetric SC of 348.8 F/g with 89.2% CR after 5000 cycles. Furthermore, they exhibited that the energy and power densities of symmetric supercapacitors with the CMC-PANI/CNT electrode were 99.89 µW h/cm 2 and 400.02 µW/cm 2 , respectively.…”

Carbon nanotubes (CNTs), due to mechanical, electrical, and surface area properties and their ability to adapt to different nanocomposite structures, are very substantial in supercapacitor electrodes. In this review, we have summarized high-performance, flexible, and symmetry CNT supercapacitors based on the CNTs/graphene, CNTs/metal, and CNTs/polymer electrodes. To present recent developments in CNT supercapacitors, we discuss the performance of supercapacitors based on electrical properties such as specific capacitance (SC), power and energy densities, and capacitance retention (CR). The comparison of supercapacitor nanocomposite electrodes and their results are reported for future researchers.
