    A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometre range . They are one of the allotropes of carbon. Two broad classes of carbon nanotubes are recognized: Single-walled carbon nanotubes (SWCNTs) have diameters around 0.5–2.0 nanometres, about 100,000

    Carbon nanotubes can also enable shorter processing times and higher energy efficiencies during composite curing with the use of carbon nanotube structured heaters. Autoclaving is the ‘gold standard’ for composite curing however, it comes at a high price and introduces part size limitations.

    The catalytic vapor phase deposition of carbon was reported in 1952 [11] and 1959, [12] but it was not until 1993 [13] that carbon nanotubes were formed by this process. In 2007, researchers at the University of Cincinnati (UC) developed a process to grow aligned carbon nanotube arrays of length 18 mm on a FirstNano ET3000 carbon nanotube ...

    A nanotube is a nanoscale cylindrical structure with a hollow core, typically composed of carbon atoms, though other materials can also form nanotubes. Carbon nanotubes (CNTs) are the most well-known and widely studied type, consisting of rolled-up sheets of graphene with diameters ranging from about 1 to tens of nanometers and lengths up to ...

    A single-walled carbon nanotubes (SWCNT) can be envisioned as strip of a graphene molecule (a single sheet of graphite) rolled and joined into a seamless cylinder.The structure of the nanotube can be characterized by the width of this hypothetical strip (that is, the circumference c or diameter d of the tube) and the angle α of the strip relative to the main symmetry axes of the hexagonal ...

  7. Mechanical properties of carbon nanotubes - Wikipedia

    en.wikipedia.org/wiki/Mechanical_properties_of...

    Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. This strength results from the covalent sp 2 bonds formed between the individual carbon atoms. In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63 gigapascals (9,100,000 psi).

  8. Carbon nanotube chemistry - Wikipedia

    en.wikipedia.org/wiki/Carbon_nanotube_chemistry

    Carbon nanotube chemistry involves chemical reactions, which are used to modify the properties of carbon nanotubes (CNTs). CNTs can be functionalized to attain desired properties that can be used in a wide variety of applications.
