“…In the future it is expected that upon the optimization of their structure, meaning the use of only long armchair single-wall nanotubes (SWNTs) of one chirality, perfect purity, alignment and densification, the fibers/films will achieve an electrical conductivity better than copper, while being one-sixth of the weight [18,19]. Taking into account the rapid development in this area of research and successes up to date, it may be expected that this will occur within the next few years.…”

“…Firstly, none of the standard printing techniques enable the alignment of the CNTs within the printed path. We know, from the existing research, that this will not ensure the highest electrical conductivity [18,19]. The use of all armchair long-single-walled CNTs, of one chirality, should improve the conductivity but to obtain optimum contact, long connections between nanotubes need to be ensured.…”

“…A very interesting alternative to printed conductors may be spun CNT fibres and films, i.e., yarns and flat sheets made purely of axially-aligned carbon nanotubes. These lightweight fibrous all-carbon materials are characterized by very high electrical conductivity which should soon match the electrical performance of the most-conductive metals [19,[23][24][25]. Additionally, the spun fibers and films are characterized by a high thermal conductivity coupled with mechanical strength, fatigue resistance, specific surface area/porosity and flexibility.…”

Current studies of carbon nanotubes have enabled both new electronic applications and improvements to the performance of existing ones. Manufacturing of macroscopic electronic components with this material generally involves the use of printed electronic methods, which must use carbon nanotube (CNT) powders. However, in recent years, it has been shown that the use of ready-made self-standing macroscopic CNT assemblies could have considerable potential in the future development of electronic components. Two examples of these are spun carbon nanotube fibers and CNT films. The following paper considers whether these spun materials may replace printed electronic CNT elements in all applications. To enable the investigation of this question some practical experiments were undertaken. They included the formation of smart textile elements, flexible and transparent components, and structural electronic devices. By taking this approach it has been possible to show that CNT fibres and films are highly versatile materials that may improve the electrical and mechanical performance of many currently produced printed electronic elements. Additionally, the use of these spun materials may enable many new applications and functionalities particularly in the area of e-textiles. However, as with every new technology, it has its limitations, and these are also considered.

“…137 The first electrical machines based on such wiring have already been constructed. 138 CNTs are also among the strongest materials on Earth, with Young's modulus reaching 950 GPa and tensile strength up to 63 GPa. 139 There has been a lot of development of polymer-matrix composites reinforced with CNTs that not only drastically improve the mechanical properties, 140,141 but they also provide means for current conduction, which, for example, is very important in composites used for aircraft lightning protection.…”

Carbon materials are among the most commonly used components of supercapacitor electrodes. Particularly, active carbons are recognized as cheap, available, and easily tailored materials. However, the carbon family, i.e. carbon products and carbon precursors, consists of many members. In this manuscript some of these materials, including laboratory scale-produced carbon gels, carbon nanotubes and carbonized materials, as well as industrial scale-produced graphites, pitches, coke and coal, were compared. Discussion was preceded by a short history of supercapacitors and review of each type of tested material, from early beginning to state-of-the-art. Morphology and structure of the materials were analyzed (specific surface area, pore volume and interlayer spacing determination), to evaluate their applicability in energy storage. Thermal analysis was used to determine the stability and purity. Finally, electrochemical evaluation using cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy was performed. Outcomes of each analytical technique were summarized in different sections.

“…A high degree of CNT alignment will result in the magnification of the uniaxially excellent properties of individual nanotubes to macroscopic length-scales. This scalable alignment technology therefore is a strong candidate for large-area manufacturing of highly-conductive light-weight CNT yarns/wires [4] and advanced composite materials [5]. A secondary challenge is to ensure a good, strong chemical bond between the matrix and the CNT content, to enable both the transfer of mechanical strain but also to improve electrical and thermal conductivity between the matrix and the CNT [6].…”

By electrospinning poly(ethylene oxide) (PEO)-blended sodium dodecyl sulfate (SDS) functionalized carbon nanotube (CNT) solutions, we engineered single-and double-walled nanotubes into highly aligned arrays. CNT alignment was measured using electron microscopy and polarised Raman spectroscopy. Mechanical tensile testing demonstrates that a CNT loading of 3.9 wt% increases the ultimate tensile strength and ductility of our composites by over a factor of 3, and the Young's modulus by over a factor of 4, to ∼260 MPa. Transmission electron microscopy (TEM) reveals how the aligned nanotubes provide a solid structure, preventing polymer chains from slipping, as well as polymer crystallisation structures such as 'shish-kebabs' forming, which are responsible for the improved mechanical properties of the composite. Differential scanning calorimetry (DSC) and small angle X-ray scattering (SAXS) reveals micellar and hexagonal columnar structures along the axis of the fibers, some of which are associated with the presence of the CNT, where these hexagonal structures are associated with the SDS functionalization on the CNT surfaces. This work demonstrates the benefits of CNT alignment within composites, revealing the effectiveness of the electrospinning technique, which enables significantly improved functionality, increasing the utility of the composites for use in many different technological areas.
