Carbon nanotubes are cylindrical nanostructures formed from sheets of carbon atoms arranged in a hexagonal lattice and rolled into seamless tubes with diameters on the nanometer scale. They exist as single-walled tubes consisting of one such cylinder and multi-walled tubes composed of several concentric cylinders. The direction in which the graphene sheet is rolled, described by its chirality, determines whether a nanotube behaves as a metal or a semiconductor, giving the material a remarkable range of electronic properties. Their structure confers exceptional characteristics: very high tensile strength and stiffness relative to their weight, together with excellent electrical and thermal conductivity. These properties make carbon nanotubes attractive for electronics, energy storage, sensors, and especially as reinforcing fillers in composite materials. Incorporating single-walled nanotubes into ceramic and metal-carbide matrices, for instance through advanced sintering processes, aims to improve the mechanical performance and toughness of the resulting nanocomposites. Research addresses the synthesis, purification, and characterization of nanotubes, the control of their structure and dispersion, and the relationship between their atomic arrangement and bulk behavior. Challenges include achieving uniform quality, integrating nanotubes effectively into host materials, and understanding their interactions at interfaces. As a benchmark nanomaterial, carbon nanotubes continue to drive developments across materials science, chemistry, and nanotechnology.
