Application of  MWCNT powder:

Single-walled carbon nanotubes can be basically divided into two types and multi-walled. Although they look very similar at first glance, their production methods and performance are different. The structure of nanotubes determines that they have metallic or semiconductor properties. About two-thirds of single-walled nanotubes are semiconducting, and one-third are metallic. As for multi-walled nanotubes, it is difficult to distinguish them due to the superimposition of shell properties, but they are usually metallic.

The mechanical properties of carbon nanotubes are outstanding. The average elastic modulus mwcnt measured now is 1.8 TPa. The experimental value of tensile strength of carbon nanotubes is about 200 GPa, which is 100 times that of steel and 20 times that of carbon fiber. The bending strength of carbon nanotubes is 14.2 GPa. Although the tensile strength of carbon nanotubes is high, it is not as brittle as carbon fiber. About 1% of the deformed carbon fibers will break, and about 18% of the carbon nanotubes will break when deformed. The interlaminar shear strength between carbon nanotubes is as high as 500MPa, which is an order of magnitude higher than conventional carbon fiber reinforced epoxy resin composites.

In terms of electrical properties, carbon nanotubes used as polymer fillers have unique advantages. Adding a small amount of carbon nanotubes can greatly improve the conductivity of the material. Compared with adding conventional carbon black to the resin, in order to improve conductivity, carbon nanotubes have a high aspect ratio. Therefore, the volume content of carbon black is reduced by a comparable number of spheres. The average aspect ratio of MWCNT is about 1000; at the same time, because the length of the nanotubes themselves is very short and the soft music is good, they will not break when you fill the polymer matrix, so they can maintain their high aspect ratio.
