Abstract
A preparation method of a copper-based graphene composite with high thermal conductivity is provided. A new electrodeposited solution is used for direct current (DC) electrodeposition at a reasonable electrodeposition frequency, which fabricates a new copper-based graphene composite with high tensile strength and thermal conductivity. The copper-based graphene composite prepared by electrodeposition has high thermal conductivity of 390-1112 W/(m·k) and tensile strength of 300-450 MPa, which meets the requirements in the field of thermal conduction.
