Problems solved by technology

However, the cost of precious metal silver is relatively high, which can easily lead to the enrichment of precious metals in the human body, resulting in potential dangers such as precious metal poisoning.
In the patent 201410354504.3, the researchers used the method of melt spinning to prepare polyester conductive fibers, but this method needs to modify the graphene first and the conductivity of the obtained fibers is reduced.

Abstract

The invention discloses a preparation method of a graphene composite conductive fiber and relates to the technical field of graphene. The method comprises the following steps: processing a common textile polymer fiber with an organic solvent to remove impurities such as an oiling agent on the fiber surface; dipping the textile polymer fiber into an alkali liquor and an oxidized graphene solution, and enabling the fiber surface to fully contact the oxidized graphene; and dipping the dried fiber with an oxidized graphene coating into a solution containing a reducing agent to obtain the graphene composite conductive fiber. By adopting a simple dip coating method, the obtained composite fiber has mechanical property, high temperature resistance and flexibility performance of a traditional high polymer material and also has good conductivity. The method is easy to operate, environment-friendly and convenient to industrialize.

Description

Technical field: [0001] The invention relates to the technical field of graphene, in particular to a method for preparing a graphene composite conductive fiber. Background technique: [0002] Conductive fibers not only have the mechanical properties of traditional fibers, but also have good electrical conductivity, durability, and durable antistatic properties under low humidity conditions. Since its appearance in the 1960s, it has been a hot research topic. With the deepening of research, people have developed a series of conductive fibers for textiles, and their products are widely used in intelligent textile clothing, antistatic fabrics, electromagnetic shielding fabrics, detection and camouflage materials, etc. Conductive fiber usually refers to a specific resistance lower than 10 in a standard environment (temperature 20°C, humidity 65%) 7 Ω·cm. At present, according to the material composition, it can be divided into: metal fiber, carbon fiber (carbon black), non-co...
