Carbon nanotubes are divided into different types according to different standards. Carbon nanotubes are formed after the graphene sheets are curled. Therefore, if we divide them according to the number of layers of graphene sheets, we can divide them into single-walled carbon nanotubes and multi-walled carbon nanotubes. According to the internal structural characteristics of carbon nanotubes, carbon nanotubes can be divided into sawtooth-shaped carbon nanotubes, armchair-shaped carbon nanotubes and other types.
How were carbon nanotubes discovered? Carbon nanotubes were discovered in the laboratory in 1991 by Japanese physicist Yoshiko Hiroshima. As usual, Yoshima Yoshino, who works in the NEC laboratory of Tsukuba in Japan, was observing the carbon fiber made by the arc method by using the transmission electron microscope, and unexpectedly found "carbon nanotubes". Carbon nanotubes are a kind of "tubular" carbon molecules, whose skeleton is honeycomb-shaped structure.
In China's electronic silicon carbide single crystal growth furnace, powder resistivity is an important index to characterize the electrical conductivity of materials. The lower the resistivity, the better the electrical conductivity of products, under the pressure of 20Mpa, the powder resistivity value of whisker carbon nanotubes can reach below 8mΩ · cm, and the resistivity of ordinary carbon nanotubes is above 15mΩ · cm, the resistivity of conductive carbon black is above 100mΩ · cm, and the resistivity of whisker carbon nanotubes is the lowest, which can ensure ultra-high conductivity on lithium ion batteries and composite materials.
