Problems solved by technology

Graphene can conduct electricity and heat. Since low temperature conditions such as ice and snow environments usually affect the operation of vehicles and the performance of cables and other products, graphene can be used to improve the above problems. Higher technology is required in existing heat conduction technologies The above effects can only be achieved if the content is high, and the cost is high, which is not conducive to popularization

Abstract

The invention discloses graphene metal as well as a preparation method and a product thereof, and belongs to the technical field of graphene. The graphene metal is prepared from the following raw materials in percentage by weight: 0.1-1wt% of a graphene material and the balance of a metal material, wherein the graphene material is nano graphene with 10 layers or less. The graphene metal is low in cost, has relatively good electric conduction and heat conduction properties, and has good mechanical properties. The graphene metal carbon fiber prepared from the carbon fiber and the graphene metal has better mechanical properties and weldability. Correspondingly, carbon fiber skin prepared from a skin matrix containing the graphene metal carbon fiber has better tensile property, and metal fatigue caused by vibration can be prevented. A heat conduction system comprising a power supply, an electric energy and heat energy converter and the graphene metal carbon fiber can generate heat after being electrified, so that damages to vehicles, traffic rails or cables caused by low temperature can be prevented.

Description

technical field [0001] The invention relates to the technical field of graphene, in particular to a graphene metal and its preparation method and product. Background technique [0002] Graphene is a sp 2 A new material in which hybrid-connected carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure is considered to be a revolutionary material in the future. Graphene can conduct electricity and heat. Since low temperature conditions such as ice and snow environments usually affect the operation of vehicles and the performance of cables and other products, graphene can be used to improve the above problems. Higher technology is required in existing heat conduction technologies Content just can realize above-mentioned effect, and cost is high, is unfavorable for popularizing. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] One of the objectives of the present invention is to provide a ...
