Abstract

The invention discloses a preparation method of a carbon nanotube fiber loaded nano iron oxide composite material. The method comprises the following steps of (1) dissolving ferrocene in an organic solvent to prepare a ferrocene solution; (2) carrying out film drawing on a carbon nanotube array by adopting an array spinning method to form a carbon nanotube film, twisting the carbon nanotube film to prepare carbon nanotube fibers, and spraying the ferrocene solution obtained in the step (1) on the surface of the formed carbon nanotube film in the film drawing process; and (3) performing Joule heat treatment on the carbon nanotube fibers prepared in the step (2) in a protective atmosphere. The carbon nanotube fiber loaded nano iron oxide composite material prepared by the method has a good application prospect in the fields of preparation of capacitors, catalysis, electrode materials and the like.

Description

technical field [0001] The invention belongs to the technical field of carbon nanotube composite materials, and in particular relates to a preparation method of carbon nanotube fiber-supported nano-iron oxide composite materials. Background technique [0002] Carbon nanotubes have excellent mechanical, electrical and thermal properties. It is an important means to expand its application to prepare it into a fiber with a macroscopic structure. As a new type of fiber material, carbon nanotube fiber has many functional characteristics such as light weight, good electrical conductivity, and strong toughness. Nano Fe 2 o 3 Chemically stable, it not only has the advantages of light resistance, chemical corrosion resistance, non-toxicity, etc., but also has good dispersibility, tinting strength and ability to absorb ultraviolet rays. Nano Fe 2 o 3 At the same time, it has the properties of iron oxide and nanometer materials, and is a multifunctional nanometer oxide material. ...
