Welcome to Henan KeLaiWei New Material co.,ltd!
Manufacturing Method:
Whisker carbon nanotubes are a type of multi-walled carbon nanotubes, also called carbon nanofibers, which are produced using transition metals as catalysts using floating-catalyzed chemical vapor deposition, and the products have very excellent physical and chemical properties.
Differences with conventional multi-walled carbon nanotubes:

Traditionally produced multi-walled carbon nanotube products try to bend the structure, serious agglomeration, dispersion difficulties, in the process of use need to be dispersed into the liquid to use.
Whisker carbon nanotubes products after 2900 ℃ high temperature treatment, with high purity and crystallinity, linear structure, not entangled with each other, easy to dispersed, can be directly used as dry powder, without the need to prepare into a dispersed liquid, the product has a very high thermal conductivity, which can greatly enhance the electrical and thermal conductivity of the material and mechanical properties.
