摘要： The present invention relates to a composite material for improving metal conductivity and a method of preparing the same. The composite material includes a composite of n A-B-A structures, where A is a graphene fragment layer, B is a metal foil layer, and n is an integer greater than or equal to 2; and the graphene fragment layer includes graphene fragments uniformly laid flat on the metal foil layer. The conductivity of the conventional metal material is increased by at least 18%, and the conductivity of the conventional metal material in a bending state remains almost the same as in a normal state.
