Abstract

The invention relates to preparation method of aminated carbon nanotube with high dispersibility / nylon 66 composite material, which belongs to the material technology field. The preparation method comprises the following steps that firstly, acidification is performed to the carbon nanotube to produce carbon nanotube carried with a carboxyl group, and a series of surface modification is further performed to the carboxylated carbon nanotube, to prepare the amido carbon nanotube carried with the amine groups. The aminated carbon nanotube is polymerized with hexanediamine and adipic acid through the in-situ polymerization method, to ensure the amine groups on the carbon nanotube to take part in the polycondensation reaction, so as to obtain the required products. The invention improves the dispersilbility and the interface bonding force of the carbon nanotube in the nylon 66, and obtains the aminated carbon nanotube with good dispersion property / nylon 66 composite material.

Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a preparation method of a highly dispersed aminated carbon nanotube / nylon 66 composite material. Background technique

[0002] Carbon nanotubes have very excellent mechanical properties. The strength of carbon nanotubes is 2 to 3 orders of magnitude higher than that of common polymer reinforcement materials such as ordinary carbon fibers or glass fibers, and the toughness is very high. Therefore, carbon nanotubes are ideal quasi-materials for composite materials. One-dimensional lightweight reinforced functional materials. If carbon nanotubes can be uniformly added to some matrix to form a composite material, its performance can be greatly improved, and it is an ideal lightweight reinforcing fiber for composite materials.

[0003] Nylon 66 is one of the varieties with the earliest development, the largest output and the widest application in the series of nylon pro...
