Abstract
The utility model relates to equipment manufacturing carbon nanotube by arc process, which changes the shape of the negative electrode in reacting cavity in the conventional arc process, and provides a novel electrode device by changing the graphite rod-type cathode into the graphite plate-type one in reacting cavity in the conventional arc process based on the prior manufacturing equipment; the plate diameter is larger than that of the electric arc. The manufacturing equipment in the utility model has more reasonable heat conducting distribution in generating SWNT (Single-walled Nanotube), can manufacture the SWNT with high yield, less flaws and high purity.
Description
Technical field
The utility model relates to preparation carbon nanotube equipment, refers to preparing carbon nano tube by arc process novel electrode device especially, and the productivity of Single Walled Carbon Nanotube and purity are improved.
Background technology
Carbon nanotube is a most important novel material in the current field of nanometer technology.It is a diameter 1-20 nanometer, several microns of length the One-dimensional Quantum material, the branch of single wall and multi-walled carbon nano-tubes is arranged, arc process is to prepare one of main method of Single Walled Carbon Nanotube at present in the world.Traditional arc process is in being filled with the reaction cavity of certain rare gas element, produces electric arc between two root graphite electrode rods, rearranges under high arc temperature and catalyst action by carbon atom, obtains Single Walled Carbon Nanotube in resultant.Resultant is rubber film shape, netted, precipitates respectively and is suspended on the reaction chamber wall and the axial surface of negative electrode graphite rod.Then collect bird's nest shape porous throw out at the end face of negative electrode graphite rod.The Single Walled Carbon Nanotube that on this device basic, obtains, productive rate is low, and defective is many, and impurity is many, has hindered carbon nanotube is carried out further developing of scientific research and application.
Summary of the invention
The utility model provides a kind of preparing carbon nano tube by arc process novel electrode device, has improved the productive rate and the purity that are equipped with Single Walled Carbon Nanotube with the electric arc legal system.
For reaching above-mentioned purpose, the technical scheme of the utility model technical solution problem is: on the basis of original preparation facilities, replace traditional bar type negative electrode Graphite Electrodes with flat graphite (thin plate Polygons) or other metal sheet cathode electrode, described plate electrode, its diameter must be greater than the electrical discharge arc diameter.As, the anode graphite torch is diameter 6mm, the diameter of negative electrode graphite electrode plate (being plate electrode) is greater than more than the 30mm, desirable 100-150mm, thickness 10mm.
Superior effect of the present utility model is: it is more reasonable that thermal conduction distributes, make the rubber film shape resultant that is deposited in originally on bar type negative electrode axial surface and the reaction cavity inwall focus on the radial surface of flat negative electrode, the reticulated structure thing that was suspended on originally on the reaction cavity inwall has been hanging to around the plate electrode.Through Raman scattering, scanning electron microscope, transmission electron microscope detects, the Single Walled Carbon Nanotube that contains in the resultant, defective is few, purity height, productive rate height.Simple structure of the present utility model, productive rate height, operational safety are reliable.
