Mechanical property needs to carry out subsequent processing and heat treatment again after growing graphene, influences finally obtained graphene electric wire electricity
The performance of cable conductor.In addition, being limited by graphene growth equipment, production efficiency is low, for the stone of large-scale electric wire
Black alkene plating and growth technique difficulty are larger.The prior art also discloses a kind of preparation method of graphene wire, by copper
Surface grows graphite alkane, and graphite alkane is then reduced to graphene to prepare graphene wire.However, the patent is in preparation process
In acid need to be used to copper conductor surface clean, unfriendly to environment, and need to load plasma generator, cost is higher.It is existing
It is core to have technology to disclose a kind of copper or aluminium, and copper-graphite alkene complex phase is the electric wire of sheath, and the prior art also discloses one kind
The preparation method of copper-graphite alkene complex phase conductor wire core, however, prepared by the electric wire that the former copper-graphite alkene complex phase is sheath
It needs that copper conductor surface clean to be also electroplated in aqueous environment with acid in the process, plating unfriendly to environment
The main function of graphene is to improve the oxidation and corrosion performance of conducting wire.The copper-graphite alkene complex phase conductor wire core of the latter
Preparation method is similar to the former, is all to use the online wicking surface electro-coppering-graphene complex phase of electric plating method, only in conducting wire knot
Different from structure and moulding process, and have the shortcomings that same.The prior art also discloses a kind of copper-graphite alkene composite wood
