preparation example Construction

[0025] A method for preparing an aligned carbon nanotube-reinforced nylon composite material provided by an aspect of the embodiments of the present invention includes:

[0026] Make the unshrunk carbon nanotube aggregates directly enter the first liquid phase system, make the nylon polymer contained in the first liquid phase system fully contact and recombine with the carbon nanotubes that make up the carbon nanotube aggregates, and form A composite of carbon nanotube aggregates and nylon;

[0027] Shrinking the composite of the carbon nanotube aggregate and nylon, orienting the carbon nanotubes therein, and performing curing treatment, and then collecting the aligned carbon nanotube-reinforced nylon composite material.

[0028] Wherein, the "carbon nanotube aggregate" can be regarded as a carbon nanotube aggregate formed by aggregating a plurality of carbon nanotubes in a loose form, for example, it can be a carbon nanotube aerosol.

[0029] Wherein, said nylon can be forme...

Abstract

The invention discloses an oriented carbon nanotube reinforced nylon composite material and a preparation method and application thereof. The preparation method comprises the following steps: enablingan unshrunk carbon nanotube aggregate to directly enter a liquid phase system, and enabling nylon macromolecules contained in the liquid phase system to be in full contact and fully compounded with carbon nanotubes forming the carbon nanotube aggregate, thus forming a complex of the carbon nanotube aggregate and nylon; enabling the complex of the carbon nanotube aggregate and the nylon to shrink,enabling the carbon nanotubes in the complex to be oriented, then carrying out curing treatment, and collecting to obtain the oriented carbon nanotube reinforced nylon composite material. The preparation process is simple and controllable, the requirement of large-scale production is met, and the obtained product is excellent in mechanical property and can be used as a 3D printing material.

Description

technical field [0001] The invention relates to a preparation method of a carbon nanotube composite film or fiber, in particular to an oriented carbon nanotube reinforced nylon composite material, a preparation method and application thereof. Background technique [0002] Benefiting from the excellent mechanical, thermal, and electrical properties of carbon nanotubes, carbon nanotube composites assembled from carbon nanotubes and polymer materials also show a variety of good working properties, and are expected to be used in many fields be widely used. [0003] A variety of methods have been reported to introduce functional objects such as nanomaterials and polymer materials into materials such as carbon nanotube fibers to obtain carbon nanotube composite materials. For example, polymer materials such as nylon can be attached to carbon nanotube fibers by spraying or soaking. For another example, the carbon nanotube film can also be pulled out from the spinnable carbon nano...
