Embodiment 1
[0034] With ethanol as carbon source, ferrocene as catalyst, hydrogen and argon mixed gas as carrier gas, the heating temperature is 1500°C. exist figure 1 The spongy carbon nanotubes are collected in the device shown, and the collection time is 2 hours. By controlling the distance between the laminating device 23 and the spinning shaft 22, the thickness of the spongy carbon nanotubes is 3 cm, and the obtained density is 18.4 mg / cm 3 , the length is 750cm, and the diameter of the innermost circle is 30cm. It was characterized by scanning electron microscopy and transmission electron microscopy. figure 2 with image 3 , the results show that the sponge carbon nanotubes obtained in this example have a diameter of 2-5 nm, which is a mixture of single-walled and multi-walled carbon nanotubes.
Embodiment 2
[0036] The carbon nanotube preparation process is the same as the first embodiment. in such as figure 1 The spongy carbon nanotubes are collected in the shown device, and the collection time is 4 hours. By controlling the distance between the lamination device 23 and the distance between the spinning shaft 22, the thickness of the spongy carbon nanotubes is 3 cm, and the obtained density is 32.4 mg / cm 3 , the length is 750cm, and the diameter of the innermost circle is 30cm.
Embodiment 3
[0038] The carbon nanotube preparation process is the same as the first embodiment. in such as figure 1 The sponge-state carbon nanotubes are collected in the device shown, and the collection time is 2 hours.

Abstract
The invention provides a collection device for a sponge-state carbon nanotube. The collection device comprises a tube furnace and a collection box which is communicated with the tube furnace, wherein the tube furnace is applied to catalytic generation of a carbon nanotube film; a spinning shaft and a collecting device arranged on the spinning shaft are arranged inside the collection box; the spinning shaft can be driven to rotate, so that the carbon nanotube film catalytically generated by the tube furnace is wound on the collection device; a laminating device matched with the spinning shaft is also arranged inside the collection box; and the distance between the laminating device and the spinning shaft is adjustable. Compared with the prior art, batch collection of the large-area adjustable sponge state carbon nanotube can be realized by the collection device for the sponge state carbon nanotube disclosed by the invention, and the collection device is simple in structure, stable, reliable, high in collection efficiency, and applicable to large-scale industrial production.
