Technical Field
The invention relates to the technical field of conductive cloth manufacturing.
In particular to a carbon nano tube conductive cloth and a manufacturing method thereof.
Background
The conductive cloth can be used in the fields of electric heating, electromagnetic shielding and the like. Conventionally, the conductive cloth is made of fiber cloth (cotton cloth, polyester fiber cloth, nylon cloth, aramid cloth, etc.) as a base material, and is subjected to pretreatment and then is plated with a metal (metal silver, etc.) coating to have metal characteristics, so that the conductive fiber cloth is formed, and the metal is used as a conductive heating element. However, the metal is easy to oxidize and has heavier mass; in addition, the flexibility of the metal coating is poor, and the metal coating is easy to fall off after being bent for many times.
In recent years, carbon fiber filaments have been used as conductive cloths such as heating elements. I.e. carbon fibre tows are woven with the yarns. However, the carbon fiber tows have poor bending resistance and are easy to break, so that the conductivity is lost; and when the carbon fiber and common yarn woven cloth is electrified and heated, only the surfaces of the carbon fiber tows generate heat, and the temperature distribution is uneven.

The carbon nano tube is used as a novel material and has good mechanical, electrical and chemical properties. In recent years, the wide application prospect of the carbon nano tube is continuously shown along with the deep research of the carbon nano tube. Carbon nanotubes have a large aspect ratio (greater than 1000) and are easily formed into films. Carbon nanotubes have been applied to conductive coatings, transparent conductive films, and exhibit excellent conductive properties. In addition, the carbon nanotubes are formed by curling single-layer (single-wall carbon nanotubes) or multi-layer graphene layers (multi-wall carbon nanotubes), and graphene is a basic composition unit of different carbon materials (such as graphite, carbon nanotubes, carbon fibers and the like), and researches prove that the graphene is electrified to emit heat by far infrared. The application of the graphene far infrared electrothermal film starts to appear in the market in recent years. The carbon nano tube also has the same far infrared electrothermal property, and has the advantage of easy film formation compared with graphene. In addition, the carbon nano tube has high electric conductivity, excellent heat conductivity and good thermal stability, so the preparation of the far infrared electrothermal film by taking the carbon nano tube as a basic unit has great potential.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the advantages that: the carbon nano tube water-based ink is coated on the base material, so that the conductivity is good; when the electric heating is carried out, the temperature distribution is uniform, and the high temperature resistance is good; the bending resistance is relatively good, the bending resistance is not easy to break, and the flexibility is very good.
