Problems solved by technology

In the above studies, the impregnation method was used to prepare the carbon material polyester composite. Zhou Zhou et al. also used the impregnation method to prepare the carbon nanotube polyester composite and applied it to the antistatic research. However, the composite material prepared by this method has poor washing performance and carbon Nanotubes are easy to fall off

Abstract

The invention relates to a preparation method of a carbon nanotube / fabric flexible combined electrode material. The preparation method comprises steps of carrying out hydrophilic processing on the fabrics to obtain hydrophilic fabrics; mixing a carboxylation carbon nanotube and surfactant into deionized water and carrying out ultrasonic dispersing to obtain the carbon nanotube dispersion liquid; and arranging the hydrophilic fabrics and the carbon nanotube dispersion liquid in an infrared ray dyeing machine for processing, and carrying out cooling, cleaning and drying after the processing is finished to obtain the carbon nanotube / fabric flexible combined electrode material. The preparation method is simple to operate. The obtained composite electrode material is advantaged by light quality, high flexibility, washable ability and low price, can be used as the base material of other electrode materials and can be applied to the flexible electrode material field to improve the electrochemical performance of the electrode.

Description

Technical field [0001] The invention belongs to the field of preparation of electrochemical energy storage materials, and particularly relates to a preparation method of a carbon nanotube / fabric flexible composite electrode material. Background technique [0002] Carbon nanotubes are the earliest carbon materials used in the field of energy storage. They have a huge aspect ratio and a hollow structure, allowing them to have a large specific surface area to store a large amount of charge. In addition, carbon nanotubes have good electrical conductivity and chemical stability, so that they can provide greater cycle stability and service life when preparing energy storage materials. [0003] Current research on carbon nanotube electrode materials is mainly focused on powders and films. In the field of flexible electrode materials, researchers are more inclined to combine them with flexible substrates such as textiles. Patent CN 102704351 A mixes carbon nanotubes with a resin matrix to...
