“…The so-called conductive fibers generally refer to the fibers with resistivity below 10 7 Ω cm (200 °C, 65% RH), which can be divided into two categories mainly, intrinsic conductive fibers and composite conductive fibers. Intrinsic conductive fibers refer to the fibers with their inherent conductive ability, such as metal fiber, carbon fiber, conductive polymer fiber, [31] carbon nanotube (CNT) fiber, [32][33][34][35][36][37] graphene fiber (GF), [38][39][40][41][42][43][44][45] etc. The important potential has been demonstrated due to its good conductivity, high mechanical strength, and environmental stability.…”

Fibers and textiles are attractive substrates for constructing wearables, the devices rely on conductive fibers with good stretchability to realize electrical conductivity and mechanical adaptivity. The exploitation of stretchable composite conductive fibers (SCCFs) requires diverse strategies in material options and process methods, tackling the challenge in balancing electrical and mechanical properties for ultrafine fiber, which highly determine the properties and applications. In this article, first the working mechanism and advantages of the SCCFs in wearables is introduced. Second, different conductive fillers as well as their respective incorporation strategies and performance superiorities in fabricating SCCFs are systematically summarized. Third, the integration routes of the conductive fillers in SCCFs are indicated and compared, presenting different fabrication strategies and mechanisms for improving the performance of SCCFs. Thereafter, the typical applications of SCCFs in energy management, sensing, actuators, heaters, and displays are highlighted. Accordingly, the main challenges of SCCFs for wearable applications are indicated, and the possible solutions for challenges tackling are proposed. This review prepared aims to highlight the importance of SCCFs in wearables, and provides insights in terms of mechanism, materials, fabrication, and performance improvement, paving a referable way to promote the innovative exploitation and development of SCCFs, extending the application scenarios.

“…Therefore, increasing the length of the CNTs in the as-spun CNTFs is an effective way to improve the fiber strength. In addition, although the mechanical properties of CNTFs have been further improved by optimizing spinning and postprocessing technologies on the CNTF level (or CNT bundle level), including adjusting winding rates, solvent densification, rolling densification, acid treatment, , and particle beam irradiation, the tensile strength (<5 GPa) of CNTFs by the FCCVD spinning to date has been far below expected due to the friction and slippage between as-grown short CNTs. , The length modulation of CNTs in the as-spun CNTFs is the premise for achieving excellent performance. However, studies on the modulation of CNTs in direct spinning are still in their infancy.…”

With impressive individual properties, carbon nanotubes (CNTs) show great potential in constructing high-performance fibers. However, the tensile strength of as-prepared carbon nanotube fibers (CNTFs) by floating catalyst chemical vapor deposition (FCCVD) is plagued by the weak intertube interaction between the essential CNTs. Here, we developed a chlorine (Cl)/ water (H 2 O)-assisted length furtherance FCCVD (CALF-FCCVD) method to modulate the intertube interaction of CNTs and enhance the mechanical strength of macroscopic fibers. The CNTs acquired by the CALF-FCCVD method show an improvement of 731% in length compared to that by the conventional ironbased FCCVD system. Moreover, CNTFs prepared by CALF-FCCVD spinning exhibit a high tensile strength of 5.27 ± 0.27 GPa (4.62 ± 0.24 N/tex) and reach up to 5.61 GPa (4.92 N/tex), which outperforms most previously reported results. Experimental measurements and density functional theory calculations show that Cl and H 2 O play a crucial role in the furtherance of CNT growth. Cl released from the decomposition of methylene dichloride greatly accelerates the growth of the CNTs; H 2 O can remove amorphous carbon on the floating catalysts to extend their lifetime, which further modulates the growth kinetics and improves the purity of the as-prepared fibers. Our design of the CALF-FCCVD platform offers a powerful way to tune CNT growth kinetics in direct spinning toward high-strength CNTFs.

“…There have been numerous post-treatment approaches for the reconstruction of architectured CNT ensembles and the enhancement of their interactions, which open up avenues for effectively extending the superior properties of nanoscale CNTs to macroscopic CNTFs. The solution densification, − mechanical treatment, , and thermal annealing process , have been used to improve the packing density and orientation of CNTFs. Notably, chlorosulfonic acid (CSA) enables the side-wall protonation of CNTs and induces the remarkable volume expansion of the as-spun fibers, which offers a unique opportunity to reassemble the internal microstructures.…”

Carbon nanotubes (CNTs) are promising building blocks for the fabrication of novel fibers with structural and functional properties. However, the mechanical and electrical performances of carbon nanotube fibers (CNTFs) are far lower than the intrinsic properties of individual CNTs. Exploring methods for the controllable assembly and continuous preparation of highperformance CNTFs is still challenging. Herein, a graphene/ chlorosulfonic acid-assisted wet-stretching method is developed to produce highly densified and well-aligned graphene/carbon nanotube fibers (G/CNTFs) with excellent mechanical and electrical performances. Graphene with small size and high quality can bridge the adjacent CNTs to avoid the interfacial slippage under deformation, which facilitates the formation of a robust architecture with abundant conductive pathways. Their ordered structure and enhanced interfacial interactions endow the fibers with both high strength (4.7 GPa) and high electrical conductivity (more than 2 × 10 6 S/m). G/CNTF-based lightweight wires show good flexibility and knittability, and the high-performance fiber heaters exhibit ultrafast electrothermal response over 1000 °C/s and a low operation voltage of 3 V. This method paves the way for optimizing the microstructures and producing high-strength and high-conductivity CNTFs, which are promising candidates for the high-value fiberbased applications.
