Problems solved by technology

[0003] At present, carbon nanotube aerogels are grown by single corundum tube or quartz tube, and the production capacity and continuity are low. In terms of improving production capacity and continuity, the method of increasing the tube diameter and tube length is currently used. Or switch to a more expensive catalyst method, the process is complicated and the cost is high

Abstract

The present invention discloses a device for growth of a carbon nano-tube aerogel. The device comprises a main reaction cavity and a collection box, wherein the main reaction cavity is provided with an air inlet and an air outlet formed opposite to the air inlet; the collection box is communicated with the main reaction cavity; at least one secondary reaction cavity communicated with the main reaction cavity is sleeved in the main reaction cavity, the secondary reaction cavities are formed close to the air inlet of the main reaction cavity, and the length of each of the secondary reaction cavities in the axial direction of the main reaction cavity is less than that of the main reaction cavity. Compared with the prior art, the defect that a single reaction cavity is taken as a reaction chamber for the growth of the carbon nano-tube is overcome by virtue of sleeving the secondary reaction cavities in the main reaction cavity, so that not only is continuous and uniform carbon nano-tube aerogel generated, but also the yield of the carbon nano-tube aerogel is greatly improved by enlarging the tube diameter of the reaction chamber. The production cost is saved, the production period is shortened, and the industrial production of the carbon nano-tube aerogel becomes probable.

Description

technical field [0001] The invention relates to the field of nanomaterial manufacturing, in particular to a device for growing carbon nanotube airgel. Background technique [0002] Carbon nanotubes are another new structural form of carbon discovered in the early 1990s after C60. They are single-layer or multi-layer graphite tubes nested, hollow, and one-dimensional carbon with a diameter of several nanometers or tens of nanometers. Structural form, since it was discovered under a high-resolution electron microscope in 1991, has triggered a great research boom in the world. As a new type of nanomaterial, its unique geometric structure and electronic band structure have brought excellent Mechanical properties, electrical properties, thermal properties, and electromagnetic properties, etc., these excellent properties make carbon nanotubes have great potential application advantages. As a three-dimensional network structure composed of carbon nanotubes, carbon nanotube aerogel...
