The super-sequential carbon nanotube array is a pure carbon nanotube array formed by a plurality of carbon nanotubes which are flattened and perpendicular to the substrate growth. The super-shunned nanometer is controlled by the above-mentioned controlled growth conditions. In the carbon tube array, there is no such as miscellaneous, such as amorphous carbon or Retaining catalyst metal particles, etc. The carbon nanotubes in the array of nanopores form an array by close contact with each other by van der Waals force. The array of carbon nanotubes is substantially the same as the area of the substrate described above. The tool scrapes off the nano carbon official in the carbon nanotube array described above from the substrate to obtain a carbon nanotube raw material, wherein the nanometer stone reversely maintains a state of intertwining to some extent. In the official raw material, the length of the carbon nanotubes is greater than 1 μm.
