Background

This section provides background information related to the present disclosure only and is not necessarily prior art.

The method for improving the conductivity of copper by compounding carbon materials such as graphene is one of the mainstream strategies for preparing high-conductivity copper. In the traditional scheme, the graphene copper material is prepared at extremely high temperature (more than 1000 ℃ and close to the melting point of copper) by a static chemical vapor deposition method, but the schemes can not realize continuous production, so that the energy consumption and the cost are very high, and the scheme can not be successfully applied in the downstream field.

When the graphene is prepared, a copper foil is generally used as a catalytic substrate, and the copper foil is rolled and uncoiled simultaneously and placed in a vacuum system, so that roll-to-roll in the production process is realized, but the existing equipment has the following defects: 1. the process temperature is generally over 1000 ℃, the sealing between chambers is difficult to realize, and the valve can be protected only by cooling through a long non-working area; 2. in order to protect components in the high vacuum system from being oxidized, after the growth of each roll of copper foil is finished, the system needs to be cooled for a long time and then the sealing cabin door needs to be opened; 3. the growth speed of the graphene is slow, namely the moving speed of the copper foil in a vacuum system is slow, and the production efficiency is very low; 4. the method mainly uses hydrogen (which can cause 'hydrogen disease' to reduce the performance of copper materials in the copper processing process) as protection, and uses gases such as methane and the like as carbon sources, wherein the gases belong to flammable and explosive products.
