Abstract

This invention relates to a device for continuously synthesizing nm carbon materials including a first vacuum cavity, a second and a third vacuum cavities and a loader, in which, said second and third vacuum cavities realize on-off with the first via a valve, the first one contains an anode, an exhaust port and a conductor moving relatively to the first one, said second one includes a pump port and a control device, said third vacuum cavity includes a pump port, said loader includes a tank containing cathode, an electrode hole conducting to the tank and a cathode in the tank, in which, said control device sends said loader in said second vacuum cavity into the first and third vacuum cavities and the conductor can be connected with the cathode via said electrode hole when the loader is placed at a preset position in said vacuum cavity. This invention also provides a synthesizing method for the nm carbon material.

Description

【Technical field】 [0001] The invention relates to a device and method for synthesizing nano-carbon materials, in particular to a device and method for synthesizing nano-carbon materials by using an arc discharge method. 【Background technique】 [0002] The arc discharge method is the earliest technology used in the synthesis of nano-carbon materials (including nano-carbon powder, nano-carbon tubes, nano-carbon fibers, nano-carbon spheres or their mixtures, etc.), which uses the high temperature generated by arc discharge to vaporize the raw materials to deposit methods for nanomaterials. Due to its high mechanical strength and excellent chemical and physical properties, nano-carbon materials have been used in many fields. [0003] In 1991, Japanese researcher Iijima Sumio (Iijima) and others first used the arc discharge method to synthesize carbon nanotubes. In a vacuum chamber, two graphite carbon rods are used as an anode and a cathode opposite to the anode, and the dista...
