The production of continuous fibers made purely of carbon nanotubes has paved the way for new macro‐scale applications which utilize the superior properties of individual carbon nanotubes. These wire‐like macroscopic assemblies of carbon nanotubes were recognized to have a potential to be used in electrical wiring. Carbon nanotube wiring may be extremely light and mechanically stronger and more efficient in transferring high frequency signals than any conventional conducting material, being cost‐effective simultaneously. However, transfer of the unique properties of individual CNTs to the macro‐scale proves to be quite challenging. This Feature Article gives an overview of the potential of using carbon nanotube fibers as next generation wiring, state of the art developments in this field, and goals to be achieved before carbon nanotubes may be transformed into competitive products.

“…20 The electrospinning device consisted of a syringe-type infusion pump (MCIP-III, Minato Concept, Tokyo, Japan) and a high-voltage regulated DC power supply (HAR-100P0.3, Matsusada Precision, Kusatsu, Japan). We used a rotating disk as a collector to align the electrospun fibers (disk diameter: 250 mm, width: 3 mm).…”

“…2,3 In particular, the applied voltage and the flow rate are crucial factors for controlling the fiber diameter. [20][21][22] In the present study, the applied voltage for the spinning and flow rate of the solution were set at 11.0-39.5 kV and 0.1-0.5 ml min À1 , respectively. The nozzle-to-collector distance was fixed at 10 or 12 cm, and the rotating speed of the collector was 500 r.p.m.…”

Liquid crystal polymer (LCP) nanofibers were prepared by electrospinning from isotropic and biphasic poly(c-benzyl-L-glutamate) (PBLG)/dichloromethane-pyridine solutions. The prepared fibers were characterized by scanning electron microscopy, Fourier-transform infrared spectroscopy, polarized optical microscopy, wide-angle X-ray diffraction and polarized micro-Raman spectroscopy. The as-spun PBLG fiber from the isotropic solutions had an undulating orientation of closed-packed a-helices similar to a serpentine trajectory in their internal structures. The as-spun PBLG fibers from the biphasic solutions that contained the LC phase had uniaxially oriented hexagonal lattices of a-helices along the fiber axis. These results indicated that the orientation of the ordered structure of the electrospun lyotropic LCP fibers can be controlled by the initial microstructure of the spinning solution.

“…The fabrication methods of CNT fibers can be mainly classified into two categories—wet (liquid) spinning and dry (solid) spinning 9a,57. Other methods, including electrospinning, are probably of little importance due to either the low electrical performance of the as‐prepared CNT fibers, the complexity of manufacturing processes, or higher cost.…”

and environmentally friendly conductive cables or wires as a replacement for copper. From this view, carbon-based nanomaterial is a potential candidate.Carbon related nanomaterials including fullerenes, carbon nanotubes (CNTs), and graphene are promising due to their exceptional conductive and electronic transport properties, which may accelerate the practical and potential applications for various kinds of novel engineering areas spanning from electronics, energy storage, and advanced materials to nanotechnology and biotechnology. Among the family of carbon nanomaterials, CNTs have been a particularly attractive material since its discovery in 1991 by Iijima, [1] due to their nanoscale 1D shape, excellent mechanical properties, tunable electrical properties either metallic or semiconducting, high current carrying capacity, and many other exciting properties. These properties have highlighted the potential of CNTs use in a plethora of applications, including electrically conductive fillers in polymer composites, flexible and transparent conductive films, microelectronics (transistors, interconnectors, heat dissipaters), and lightweight conducting wires and cables. [2] Figure 1 points out the forecast presented by Endo et al. [3] on the present, near future, and long term applications of CNTs in various fields. An interesting potential application of CNTs is the long-term electrical conductors, which are able to transmit power from plants to plants or households, as well as be used in electronic devices.Compared to conventional copper cables or wires, CNT based cables have several advantages including 1) a lower density of 1.3 g cm −3 for single-walled carbon nanotubes (SWCNTs) [4] and 2.1 g cm −3 for multiwalled carbon nanotubes (MWCNTs), [5] both of which are much lower than that of copper, 8.96 g cm −3 ; [6] 2) environmental stability, which can stand with severe conditions including high pressure, large temperature changes, etc.; 3) excellent mechanical performance with a Young's modulus and strength in the ranges of 1.0 TPa and 50 GPa, respectively; [7] 4) ultrahigh electrical conductivity as high as 10 8 S m −1 for SWCNTs, which is higher than that of copper (≈10 7 S m −1 )). [8] Furthermore, the limited amount of conventional conductive metal resources in nature and their soaring market price greatly increased the need for a desirable alternative solution that are abundant in nature, low-cost, andThe lack of progress to obtain commercially available large-scale production of continuous carbon nanotube (CNT) fibers has provided the motivation for researchers to develop high-performance bulk CNT assemblies that could more effectively transfer the superb mechanical, electrical, and other excellent properties of individual CNTs. These wire-like bulk assemblies of CNTs have demonstrated the potential for being used as electrical conductors to replace conventional conductive materials, such as copper and aluminum. CNT conductors are extremely lightweight, corrosive-resistive, and mechanically strong while being ...
