“…Interestingly, the authors have also demonstrated that the conductivity scales inversely proportionally to the CNT diameter for an ideal fiber. Barnett et al (2019) and Lepak-Kuc et al (2019) have shown via experimental and theoretical approaches the dependence of the electrical contact resistance at the junction regions between CNTs (SWCNTs and/or MWCNTs) and between CNTs and graphene interfaces by considering morphology, structure (i.e., chirality). Interestingly, it was shown that when there is a large…”

“…On the other hands, the addition of graphene flakes within a CNT wire to constitute a hybrid composition has been shown to increase the electrical conductivity, current-carrying capacity (or ampacity, which can be defined as the maximum current in amperes, that a conductor can carry continuously under the conditions of use and without exceeding its temperature rating) and doping properties (Li and Pandey, 2015;Lepak-Kuc et al, 2019). Besides the remarked relevance of the graphene flake characteristics, of the fiber purity and of the solvent properties, the authors explained that graphene flakes constitute effective bridges by means of a theoretical model.…”

Electrical conductors based on carbons have recently attracted a growing interest due to the prospect of replacing metals. Electrical conductors without metals could represent not only an alternative for traditional wiring, but also a step forward in the progress and advancing of technology. This result can be achieved by combining high electrical conductivity with other properties, that are dexterity, light weight, environmental stability, high strength and flexibility. As the best mechanical properties, high electrical/thermal conductivity of the assembled fibers are all generally associated with low concentration of defects in the fiber backbone and in the individual carbon "building blocks", a special attention is paid to an empirical relationship between morphology/structure/composition and the electrical properties. In this review, starting from the beginning, from the late 19th century, when the carbon filaments became the lights for urban streets, some of the recent developments in the field of "all-carbon" electrical conductors are discussed. Such conductors can be obtained by assembling nanoscale carbons (i.e., carbon nanotubes, graphene) into macroscopic fibers, yarns and ropes (hereafter fibers). In this perspective, the role played by the chemistry in particular by means of the molecularlevel control and doping, is emphasized. This contribution elucidates most recent results in the field, and envisages new potential applications.

“…There have been advances in fabricating nanocomposites composed of a multiphase solid materials, where one of the dispersed phases is in the nanometer-scale dimension [ 19 ] and the other is a major phase, such as ceramic, metals, or polymers [ 20 ]; carbon-carbon composites [ 21 ] and nanocarbon [ 22 ] are combined as a matrix material.…”

Nanocomposite materials have distinctive potential for various types of captivating usage in drilling fluids as a well-designed solution for the petroleum industry. Owing to the improvement of drilling fluids, it is of great importance to fabricate unique nanocomposites and advance their functionalities for amplification in base fluids. There is a rising interest in assembling nanocomposites for the progress of rheological and filtration properties. A series of drilling fluid formulations have been reported for graphene-derived nanocomposites as additives. Over the years, the emergence of these graphene-derived nanocomposites has been employed as a paradigm to formulate water-based drilling fluids (WBDF). Herein, we provide an overview of nanocomposites evolution as engineered materials for enhanced rheological attributes in drilling operations. We also demonstrate the state-of-the-art potential graphene-derived nanocomposites for enriched rheology and other significant properties in WBDF. This review could conceivably deliver the inspiration and pathways to produce novel fabrication of nanocomposites and the production of other graphenaceous materials grafted nanocomposites for the variety of drilling fluids.

“…This treatment can, at the same time, decrease the specific surface area/porosity [22,31,32]. Another example of this post-manufacture processing is purification and doping of fibers/films, e.g., by annealing and acid/halogen infiltration [46][47][48][49][50]. These post-treatments are conducted to achieve improvements in the performance of the CNT material and not any change in its actual function.…”

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.
