Abstract

The invention provides a heat radiation material with a graphite film and graphene composite structure and a realization method thereof and belongs to the technical field of heat radiation materials. The heat radiation material comprises a first graphene layer, a second graphene layer and a graphite film layer, wherein the first graphene layer is a physical layer arranged on one of the end surfaces of the heat radiation material and formed by graphene; the second grapheme layer is a physical layer which is corresponding to the first graphene layer, is arranged on the other end surface of the heat radiation material and is formed by graphene; and the graphite film layer is a physical layer arranged between the first grapheme layer and the second grapheme layer in a manner of an interlayer and formed by a graphite film. The invention has the beneficial effects that the heat radiation material is high in heat radiation performance; the advantages of the graphite film and the graphene as the heat radiation material can be mutually combined; and the heat radiation material is applied to the heat radiation field, but not limited to the heat radiation.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation materials, but is not limited to the application of heat dissipation. Background technique [0002] Electronic products, machinery, electric power, communication, chemical industry and many other fields will generate different amounts of heat in the process of product processing, production and use. Moreover, if the generated heat cannot be effectively dissipated, it may affect the processing and use of the product. [0003] At present, various heat dissipation materials have been widely used. Different types of heat dissipation materials have different properties. For example, metal materials have good thermal conductivity, especially some metal materials, such as copper, aluminum, silver, etc., have particularly good thermal conductivity. Radiators made of these metals, such as copper radiators and aluminum radiators, are widely used. [0004] The thermal conductivity properties of s...

Problems solved by technology

[0011] However, the existing high thermal conductivity graphite film also has shortcomings. Although the high thermal conductivity graphite film has a certain folding resistance, the strength between the materials is weak, and it can be easily torn or damaged due to the displacement of the adhered parts. Phenomenon, or exfoliation of surface substances, etc.
