Problems solved by technology

[0003] However, due to the small size of pores in carbon nanotube yarns and no active functional groups on the surface, thermoplastic macromolecular resins can hardly enter the interior, which limits the fabrication and application of carbon nanotube aggregate composites.

Abstract

The invention provides a preparation method of a multifunctional carbon nanotube composite yarn. The method comprises the following steps: firstly, the carbon nanotube yarn is added to a mixed solution of a bulking agent, a compatilizer and a resin matrix, and the mixed solution is left to stand; the bulking agent in the mixed solution can be decomposed to generate micro bubbles when permeating into the inside of the carbon nanotube yarn, and micro blasting effect is produced, so that the structure of the carbon nanotube yarn is gradually loosened, and an impurity removal effect is achieved; resin matrix molecules or nanoparticles enter the yarn, and initial carbon nanotube composite yarn is formed; the initial carbon nanotube composite yarn is heated and dried and is compact in structureand cured by core suction force generated in the evaporation process of the mixed solution, and the multifunctional carbon nanotube composite yarn is prepared. The method is simple and easy to implement and low in cost, and industrialization can be achieved; the prepared composite yarn has important applications in the fields of intelligent yarn, linear electrodes, intelligent fabrics and the like.

Description

technical field [0001] The invention relates to a preparation method of multifunctional carbon nanotube composite yarn. Background technique [0002] Carbon nanotubes are one-dimensional quantum materials with a special carbon six-membered ring structure. The radial dimension is on the order of nanometers, and the axial dimension is on the order of micrometers. It has excellent mechanical, electrical and thermal properties. With the development of nanotechnology, carbon nanotubes can be directly prepared into yarns by chemical vapor deposition and other means. Carbon nanotube yarns inherit the excellent properties of carbon nanotubes. Carbon nanotube yarns can be woven or composed of engineering and application materials of various structures, and have very broad application prospects. [0003] However, due to the small size of pores in carbon nanotube yarns and no active functional groups on the surface, thermoplastic macromolecular resins can hardly enter the interior, w...
