▎ 摘　　要

NOVELTY - The material (10) has a graphene-filler composite that is provided with the graphene layers (14) that are separated each other by a filler layer (12) made of copper. The graphene-filler composite is provided with a homogenous mixture of graphene and filler. The graphene-filler composite is configured to form a conductive portion, a wire, and a heat sink. USE - Graphene-filler composite material for use as conductive elements such as wire, heat sink, circuit interconnect, heat exchanger tube and fin. ADVANTAGE - The graphene existing as continuous directional monolayers is amenable to electron beam additive manufacturing primarily due to the requirement that both electron beam additive manufacturing and chemical vapor deposition (CVD) are performed under similar vacuum conditions. Thus, the integration of CVD tube furnace into the electron beam additive manufacturing system ensures the fabrication of continuous directional monolayers of graphene with enhanced electron transport. The combination of particle temperature, velocity, and size are selected so as to allow spraying at a temperature far below the melting point of the premixed powdered copper and graphene resulting in a layer of particles in the solid state. Thus, the deleterious effects of high-temperature oxidation, evaporation, melting, crystallization, residual stresses, de-bonding, and gas release are reduced or eliminated effectively while providing strong bond strength on coatings and substrates. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing graphene-filler composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the multilayer composite. Graphene-filler composite material (10) Filler layer (12) Graphene layers (14)
