The invention belongs to the technical field of
new materials, and relates to a single-walled
carbon nanotube continuous preparation
system and a process method, the device is formed by connecting a high temperature
reaction chamber and a cooling unit in series, and vacuum, gas circuit, control, cooling and feeding systems and the like are used for assistance. According to the preparation method,a
metal catalyst serving as a counter
electrode is evaporated to form tiny catalyst particles by utilizing high temperature generated by direct-current arc
flame, the tiny catalyst particles are rapidly combined with a high-temperature cracked organic
carbon source to catalyze to generate single-walled carbon nanotubes, the single-walled carbon nanotubes are cooled and then enter a gas-
solid separator, the obtained single-walled carbon nanotubes are enriched and separated by utilizing a
magnetic field, and finally, the gas-
solid separator is subjected to back-blowing by adopting
inert gas to obtain a final product. According to the method, the catalyst can exist in the form of ultrafine particles in a high-temperature growth state, strict regulation and control on the purity, the
pipe diameter structure and the like of the single-walled
carbon nanotube are truly realized, and the high-quality single-walled
carbon nanotube is continuously prepared. The device and the process are high inproduction efficiency and have important industrialization value.
