Problems solved by technology

This leads to: on the one hand, graphene cannot be strongly supported by the supporting substrate, and it will be broken when touched; on the other hand, the physically adsorbed dopant molecules are desorbed from the surface of graphene under the influence of thermal vibration of graphene, making graphene Electrical performance is unstable and rapidly deteriorating

Embodiment Construction

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0027] like figure 1 As shown, a transparent conductive composite film shown in the present invention includes a graphene film 2 and a parylene film 3 , and the parylene film 3 is arranged on one side of the graphene film 2 . The graphene film 2 and the parylene film 3 are fixedly connected by intermolecular forces.

[0028] The preferred technical solution is: the thickness of the parylene film 3 is 2-100 μm. The composition of the parylene film 3 is parylene and / or poly-3-chloro-para-xylylene and / or poly-2,5-dichloro-para-xylylene and / or polyfluoro-para-xylylene.

[0029] like Figure 4 Shown, a kind of manufacture method of transparent conductive composite film comprises the following steps:

[0030] Step 1 S...

Abstract

The invention relates to the technical field of graphene materials and particularly relates to a transparent conductive composite film comprising a graphene film and a poly-p-xylylene film, wherein the poly-p-xylylene film is arranged on one surface of the graphene film. The transparent conductive composite film has the beneficial effects that the transparent conductive composite film is provided; the graphene film is supported by the poly-p-xylylene film, so that the tight molecular contact between the poly-p-xylylene film and graphene can be realized; and an effective mechanical supporting effect on graphene is taken under pi-pi coupling action, so that the thermal vibration of graphene can be remarkably inhibited, furthermore, the electrical property of graphene is stabilized, and the service performance of graphene is greatly improved.

Description

technical field [0001] The invention relates to the technical field of graphene materials, in particular to a transparent conductive composite film. Background technique [0002] In recent years, graphene, as a new functional material, has attracted worldwide attention due to its excellent physical properties. With the development of graphene preparation and application technology, all walks of life have gradually realized the revolutionary opportunity brought by this material, especially the characteristics of extremely high optical transmittance and ultra-high carrier mobility, which are transparent conductive materials. The performance breakthrough provides a new direction. [0003] At present, the method with mature technology and capable of producing graphene in large area is chemical vapor deposition (CVD). Graphene prepared by CVD is spliced ​​from graphene single wafers with a size of several microns to tens of microns. The existence of many grain boundaries greatl...
