Features of multi-walled carbon nanotubes ：

Carbon
nanotubes (multi-walled carbon nanotubes) are graphite sheets composed
of a layer of carbon atoms rolled into a seamless, hollow tube at a
certain angle. Carbon nanotubes are another allotrope of carbon
discovered after C60. Its radial size is small. The outer diameter of
the tube is generally from a few nanometers to tens of nanometers, און
the inner diameter of the tube is lower, and some are only about 1nm;
Its length is generally in the micron level, and the ratio of height to
diameter is huge, reaching 103 to 106. Therefore, carbon nanotubes are
considered to be a typical one-dimensional nanomaterial.

Application of multi-walled carbon nanotubes: 

Carbon
nanotubes may become a new type of high-strength carbon fiber material,
which not only has the inherent nature of carbon materials. It also has
the electrical and thermal conductivity of metal materials, the heat
and corrosion resistance of ceramic materials, and the wearability of
textile fibers. And the lightweight and secure processing of polymer
materials. Using carbon nanotubes as a composite material reinforcement
is expected to exhibit good strength, elasticity, fatigue resistance,
and isotropy. It can be assumed that carbon nanotube reinforced
composite materials may bring a leap in composite performance. The
research on using nanotubes to make composite materials was first
carried out on metal substrates, such as Fe/carbon nanotubes, Al/carbon
nanotubes, Ni/carbon nanotubes, Cu/carbon nanotubes, etc. The research
focus of carbon nanotube composite materials has shifted to
polymer/carbon nanotube composite materials. פֿאַר בייַשפּיל, in a
lightweight and high-strength materials, carbon fiber is used as a
reinforcing material. The mechanical properties of carbon nanotubes and
their small diameter and large The aspect ratio will bring better
enhancement effect.
