Problems solved by technology

[0003] However, in the process of power transmission, the electrical conductors used for power transmission have high resistance, resulting in large power loss, which in turn leads to a reduction in power transmission efficiency and a narrowing of the distribution range of the power grid.
Therefore, the existing electrical conductors used for power transmission have the problems of high resistance, large power loss, low power transmission efficiency, and the reduction of the distribution range of the power grid.

preparation example Construction

[0068] The preparation method of the layered structure 3 is to first stack one or more layers of graphene particles and one or more layers of substrate layers 2 to form a sheet structure in which graphene particle layers and substrate layers 2 are alternately connected; then The sheet-like structure is compressed so that the graphene particles between the two substrate layers 2 are compressed and arranged to form a graphene layer 1 .

[0069] The compressing the sheet-like structure includes mechanically deforming the sheet-like structure using a mechanical deformation process that applies component forces perpendicular and parallel to the graphene layer; the mechanical deformation process is any one of rolling, extrusion or drawing or more.

[0070] The lamination comprises one or more repeated depositions of one layer of graphene particles on one layer of substrate layer 2; then one layer of substrate layer 2 is laminated on one layer of graphene particles; After the bottom...

Abstract

The invention discloses a graphene-based electric conductor and a preparation method thereof. The graphene-based electric conductor comprises a layered structure; the layered structure comprises graphene layers (1) and substrate layers (2) which are alternately arranged; and each graphene layer (1) is compressed between two adjacent substrate layers (2). The preparation method of the graphene-based electric conductor includes the following steps that: one or more graphene layers are laminated with two or more substrate layers, so that a graphene layer and substrate layer alternately connected sheet can be formed; and the sheet is compressed, so that the graphene layer can be compressed between two adjacent substrate layers, so that a layered structure can be formed, and the graphene-based electrical conductor is obtained. The graphene-based electric conductor of the invention has the advantages of low resistance and small electric power loss. With the graphene-based electric conductor and the preparation method thereof adopted, power transmission efficiency can be improved, the distribution range of a power grid can be expanded, and compression processing can be facilitated.

Description

technical field [0001] The invention relates to a graphene-based electrical conductor and a preparation method thereof, in particular to a low-resistance graphene-based electrical conductor suitable for cables, transmission lines, transformers and electrical equipment and a preparation method thereof. Background technique [0002] The transportation and distribution of electricity in most urban environments relies on an electrical grid consisting of transmission lines and distribution grids. Electricity transmission is the large transfer of electricity from generating plants to substations located close to demand centers. [0003] However, in the process of power transmission, the existing electric conductors for power transmission have high resistance, resulting in large power loss, which in turn leads to a reduction in power transmission efficiency and a narrowing of the distribution range of the power grid. Therefore, the existing electrical conductors used for power tra...
