Problems solved by technology

Due to the disorderly distribution of carbon nanotubes, light cannot be effectively transmitted from the above-mentioned composite film, and the above-mentioned composite film of graphene and carbon nanotubes has poor light transmittance
In addition, since graphene is dispersed in the above-mentioned composite film in the form of a large number of fragments, the conductivity of the composite film of graphene and carbon nanotubes is not strong enough, and it also affects the overall strength and toughness. Application of composite film with carbon nanotubes

Abstract

The invention relates to a method for preparing a graphene carbon nano tube composite membrane structure. The method comprises the following steps of: providing a metal substrate, wherein the metal substrate comprises a first surface and a second surface which is opposite to the first surface; growing a graphene membrane on the first surface of the metal substrate by a chemical vapor deposition method; forming a macromolecular layer on the first surface of the metal substrate to cover the graphene membrane; removing part of the metal substrate to obtain a composite structure of the graphene membrane and the macromolecular layer; and compounding a supported carbon nano tube membrane structure and the composite structure of graphene and the macromolecular layer.

Description

technical field [0001] The invention relates to a preparation method of a graphene carbon nanotube composite film structure. Background technique [0002] Both carbon nanotubes and graphene are allotropes of carbon and have special physical properties. As a one-dimensional nanomaterial, carbon nanotubes are light in weight, perfectly connected in a hexagonal structure, and have many special mechanical, electrical and chemical properties. Graphene is a single-layer two-dimensional planar structure in which carbon atoms are closely arranged in a honeycomb lattice according to regular hexagons. It has strong electrical conductivity, high strength, and good semiconductor properties. With the deepening of research on nanomaterials, the broad application prospects of graphene and carbon nanotube composites are constantly emerging. However, the composite films of carbon nanotubes and graphene in the prior art are prepared by firstly dispersing graphene fragments and carbon nanotu...
