Description

technical field [0001] The invention relates to the field of graphene metal materials, in particular to a method and device for controlling the conductivity of graphene metal laminated composite materials. Background technique [0002] With the continuous development of electronics, conduction and other technical fields, the requirements for the conduction performance of conductors are gradually increasing. At present, researchers have been able to obtain copper single crystals through the technology of spinning and pulling single crystals, which has higher conductivity than silver. However, the production conditions of this technology are harsh and the yield is low, which is not suitable for large-scale industrialization. Production. As a material with high electrical conductivity and high electron mobility, graphene has high expectations for its application in the technical fields of conduction and transport. Initially, researchers prepared nanocomposites by reducing gra...
