Description
Technical field
The present invention relates to a kind of carbon nanotube fabrics, and in particular to a kind of carbon nano-tube fibre knitted fabric and its preparation side
Method belongs to fibrous material technical field.
Background technology
Carbon nanotube has perfect one-dimensional tubular structure, possesses low-density, high strength, and it is excellent that electrical and thermal conductivity is good etc.
Different physical property, therefore (Nature, 1991,354,56-58) has been widely noticed since being found since 1991 by Iijima.Carbon is received
Mitron fiber is macroscopical continuous fiber that thousands of single-root carbon nano-tubes are formed along its axial arranging, has lightweight, high-strength height
Conductive, multi-functional feature, has huge application potential in various aspects such as aerospace, defence and military, electronic energies.Carbon
Nanotube fibers are the ideal materials of development high-performance and multifunctional fibre of new generation, have great war to high-end science and technology development
Slightly meaning.One of most important application form of fibrous material is fabric, therefore carbon nano-tube fibre is pushed to go further to reality
One of available strategy of application is to be woven into fabric.
The preparation method for the carbon nanotube fabric reported at present can be divided into three kinds.The first is with macromolecular fibre fabric
For frame, dip-coating or filtering carbon nanotube dispersion liquid on it, to obtain carbon nanotube fabric (Nano Lett.2010,10,
708-714；Adv.Mater.2017,1606679；106758159 A of Chinese patent CN；Chinese patent CN 106783226A).
Be for second first by the carbon nano-tube film that can be released in spinning carbon nano pipe array be coated on macromolecular fibre surface formed it is multiple
Fabric (ACS Nano 2016,10,9129-9135) is weaved into after condensating fiber again.The third be from carbon nano-tube fibre, with
Macromolecular fibre by woven mode shuffling at fabric (Adv.Mater.2016,28,10529-10538；Small 2018,14,
1702926) or by manual mode be woven into pure nano-carbon tube fabric (Adv.Mater.2010,22,692-696；
Adv.Energy Mater.2014,1401438；104240973 A of Chinese patent CN).However, the fabric that above method obtains
Mostly be not be made of completely carbon nanotube, even if having pure nano-carbon tube fabric be also manually made of, it is difficult to it is existing at
Ripe automatic weaving technology is mutually compatible with.Therefore the fabric being made of completely carbon nanotube is prepared by the weaving manner of automation
It is still a challenge.
Invention content

Step 2)：Required amount of carbon nano-tube fibre doubling is twisted, carbon nanotube yarn is obtained；
Step 3)：Carbon nanotube yarn is woven using the knitting technology of automation, obtains carbon nano-tube fibre needle
Fabric.
Preferably, floating chemical vapor deposition direct spinning is specially in the step 1)：Using ethyl alcohol as carbon source, two cyclopentadienyls
Iron is catalyst, and thiophene is growth promoter, and High Purity Nitrogen is carrier gas；The uniform of carbon source, catalyst and growth promoter will be contained
Mixed solution is injected by peristaltic pump in quartz conduit, and high temperature level tube furnace corundum pipe reactor is entered under the action of nitrogen
In, continuous carbon nano-tube macroscopic view aggregation is formed, aggregation leaves reactor under the action of nitrogen, into open atmosphere environment
In；By the continuous carbon nano-tube macroscopic view aggregation in open atmosphere environment using directly by being shrunk to carbon in the container containing water
Nanotube fibers.
Preferably, thickness, density and the porosity for the knitted fabric that the step 3) obtains pass through the straight of carbon nanotube yarn
Diameter or plying number control.
Compared with prior art, the invention has the advantages that：
(1) carbon nano-tube fibre is realized directly to weave by ripe automatic weaving technology after spinning process resultant yarn
Carbon nanotube fabric, technology maturation is reliable, easy to operate, is suitable for automation batch and prepares；
(2) carbon nano-tube fibre knitted fabric made from is made of carbon nano-tube fibre completely, and its structure and performance height
Controllably, there are the performances such as high strength ＆ high electric-conduction, high flexibility and be widely applied foreground.
