“…59 As shown in Figure 5h, the Ragone plot of the PPy VANA/ CNTF-based FSSC is compared with the counterpart based on the carbon-based fiber reported recently. The PPy VANA/ CNTF supercapacitor displays an energy density as high as 6.22 mW h cm −3 at a power density of 123.25 mW cm −3 , which are comparable to or better than those of the reported FSSCs, such as CF (9.4 mW h cm −3 at 13 mW cm −3 ), 60 MnO 2 /CF (0.22 mW h cm −3 at 400 mW cm −3 ), 61 Ti 3 C 2 T x / RGO//PANI/RGO (3.4 mW h cm −3 at 10.2 mW cm −3 ), 62 copper wire@CuO@MnO 2 //CNT@MnO 2 (0.38 mW h cm −3 at 25.5 mW cm −3 ), 63 and CFF@V 2 O 5 //CFF@AC (0.928 mW h cm −3 at 17.5 mW cm −3 ). 64 Additionally, Table S1 further shows the performance comparison of the PPy VANA/CNTF FSSC with that of the reported FSSCs.…”

Conducting polymer and carbon nanotube hybrids have been researched intensively in recent years for electrodes of fiber-shaped supercapacitors (FSSCs) toward flexible and wearable energy storage devices. Here, three-dimensional (3D) hierarchical polypyrrole (PPy)/carbon nanotube fiber (CNTF) architectures have been prepared by a facial electrodeposition method for flexible FSSC electrodes. PPy nanoparticles, vertically aligned nanowire arrays (VANAs), and nanowire networks were synthesized on CNTFs, respectively, to construct three types of 3D architectures by controlling the electrodeposition condition of PPy. The influence of the 3D architectures of PPy/CNTF electrodes on the performance of the assembled quasi-solid-state FSSCs has been carefully studied. The FSSCs with PPy VANAs showed a much higher specific capacitance than that with PPy nanoparticles because the hierarchical porous structure of PPy VANAs provides a higher accessibility of electrolytic ions and a higher Coulombic efficiency than that with the PPy nanowire network. The PPy VANA-/CNTF-based FSSCs displayed high flexibility, stability, and a specific capacitance of 178.14 F g–1 at 0.4 A g–1, which is much higher than that based on common PPy cauliflower-like film/CNTF electrodes (92.06 F g–1) and pure CNTF electrodes (8.48 F g–1) under the same conditions, demonstrating the great advantages of the 3D hierarchical structure.

“…29,30 A plasma-modified fiber is obtained by continuously bombarding it with the highenergy electrons and ions generated by gas discharge, which increases the roughness of the fiber surface, providing higher temperatures and larger contact areas. [31][32][33][34] Moreover, a large number of oxygen-containing reactive groups can be introduced to improve the reactivity of the fiber surface, so that the hydrophilicity and adhesion of the fiber surface can be improved. Further, the friction between fibers can be increased, accompanied by possible chemical reactions that can modify the fiber surface either physically or chemically.…”

Cellulose nanofiber (CNF) is an advanced bio‐nanomaterial. However, the hydroxyl groups on the surface of CNFs are highly polar, leading to its weak interfacial compatibility with natural rubber (NR). Therefore, it is necessary to organically modify CNFs by silanization to improve the interfacial compatibility between CNFs and NR, which can then be used to prepare high‐performance CNF/NR composites. In this study, the effect of plasma‐activated pre‐silanization of CNFs on the vulcanization characteristics, mechanical properties, Payne effect, and dynamic mechanical properties of CNF/NR composites is investigated. The high‐energy impact of the plasma weakens the agglomeration of CNFs and increased the fiber surface roughness, providing a larger contact reaction area for the silanization reaction between the silane coupling agent and CNFs. The results show that the prepared CNF/NR composites have excellent physical and mechanical properties and processing safety. Compared with the unmodified CNF, its DIN wear increases by 4%, tensile strength increases by 23%, reinforcement factor increases by 7%, rolling resistance decreases by 6.3%, and Mooney viscosity decreases by 17.6%. Overall, this study presents a novel approach for the high‐value utilization of CNFs and the preparation of NR composites with exceptional properties, thereby establishing a solid foundation for the application of all‐steel treads.

“…First, 1D conducting metal wires or carbon-based fibers as the current collector, [10][11][12][13] accompanied with other capacitive loadings, such as metal oxides and conductive polymers, were used. [14][15][16] For example, Li et al used Ni(NO 3 ) 2 and Co(NO 3 ) 2 as the capacitive precursors. [17] The resultant composite FSC electrode was prepared by synthesizing nickel-cobalt layered double hydroxide (Ni-Co LDH) on carbon fiber (CF) via a constant current deposition process.…”

Carbon fibers (CFs) have been innovated in the application of fiber‐shaped and wearable energy storage devices recently. However, time‐ and energy‐consuming activation process under harsh conditions is generally required to modify the surface structure of the CF. Herein, a fast and effective Joule heating activation method is proposed with the nickel–cobalt layered double hydroxide‐derived nanometal particles as the template. The resultant Joule heating‐activated CF (JACF) demonstrates excellent capacitive performance with an electrode capacitance of 268 F g−1. After assembling into a solid‐state fiber‐shaped supercapacitor (FSC), the device shows both enhanced specific capacitance and energy/power densities, as well as the long cycling stability of over 5000 cycles. The Joule heating method reported in this work is time and energy saving for CF activation compared with the traditional chemical etching or high‐temperature annealing processes, and it is promising for the large‐scale production of high‐performance fiber‐shaped and wearable energy devices.
