WebApr 23, 2024 · Other CNT applications; CNTs Electrical Conductivity. ... Others have proven theoretically that the Young’s modulus depends on the chirality and size of the SWNTs, ranging from 1.22 to 1.26 TPa. They have calculated a value of 1.09 TPa for a generic nanotube. However, when working with different MWNTs, others have noticed that the … WebJul 3, 2024 · The chiral angle dependency is more predominant in the CNT structures. On the other hand, graphene structure also exhibits the variation of the mechanical properties against chirality. In the case of CNT, zigzag and armchair structure exhibit higher ultimate strength and strain than other chiral structures.
WebSep 8, 2024 · The chirality in turn affects the conductance of the nanotube, its density, its lattice structure, and other properties. A SWNT is considered metallic if the value n-m is divisible by three. Otherwise, the nanotube is semi-conducting. A carbon nanotube (CNT) is a tube made of carbon with diameters typically measured in nanometers. Single-wall carbon nanotubes (SWCNTs) are one of the allotropes of carbon, intermediate between fullerene cages and flat graphene, with diameters in the range of a nanometre. Although not made this way, single-wall … See more Basic details The structure of an ideal (infinitely long) single-walled carbon nanotube is that of a regular hexagonal lattice drawn on an infinite cylindrical surface, whose vertices are the positions of … See more Narrowest examples If n and m are too small, the structure described by the pair (n,m) will describe a molecule that cannot be reasonably called a "tube", and may not even be stable. For example, the structure theoretically described by the … See more Many properties of single-walled carbon nanotubes depend significantly on the (n,m) type, and this dependence is non-monotonic (see Kataura plot). In particular, the band gap can vary from zero to about 2 eV and the electrical conductivity can show metallic or … See more CNTs are known to have weak dispersibility in many solvents such as water as a consequence of strong intermolecular p–p interactions.
