Embodiment Construction

[0042] In the present invention, a thin film layer is formed on the carbon layer material by means of polymer vapor deposition, and the carbon layer material can be conveniently endowed with a protective layer structure by using the thin film layer.

[0043] Specifically, the present invention provides a carbon layer material with a protective layer structure, which comprises:

[0044] The carbon layer material, preferably, is a material layer composed of graphite material and / or graphene. In addition, it can also be a layered structure composed of other carbon components, and of course it is not limited;

[0045] The polymer vapor deposition layer is a substance layer formed by performing polymer vapor deposition on the aforementioned carbon layer material, and its thickness is between 0.05-15 microns.

[0046] The preparation method of the material of the present invention will be described below in conjunction with specific examples.

[0047] Step 1, collecting the carbon ...

Abstract

The invention provides carbon layer materials with a protection layer structure and belongs to the technical field of carbon materials. The materials comprise carbon layer materials and a polymer vapor deposition layer, wherein the carbon materials are a substance layer formed by graphite materials and / or grapheme; the polymer vapor deposition layer is a substance layer formed by polymer vapor deposition on the carbon layer materials; and the thickness of the layer is 0.05-15 microns. By means of the carbon layer materials, a coating film is generated outside the carbon layer materials in a polymer vapor deposition mode to substantially reduce the thickness of the protection layer of the existing carbon layer materials so as to effectively improve the radiating efficiency of the carbon layer materials applied to the heat conduction and the occasions needing to arrange a protection layer on the carbon materials.

Description

technical field [0001] The invention belongs to the technical field of carbon materials. technical background [0002] Carbon layer materials mainly refer to thin-layer materials or bulk materials composed of carbon components. Among them, graphite film material is typical. [0003] At present, due to its excellent characteristics, including high thermal conductivity, heat resistance, corrosion resistance and high electrical conductivity, graphite film materials are widely used in heat dissipation of electronic products, heat-resistant sealing materials, heating elements and other technologies in current industrial applications. field. [0004] For example, among the currently widely used handheld terminals, smartphones, due to their small size, high density of electronic components, and large heat generation, need to use materials with high heat dissipation, light weight, and stable performance to achieve heat dissipation. In practical applications, graphite film materia...
