The Preparation and Properties of In Situ Grown Oriented Nitrogen-Doped Graphene-like/Copper Composite Materials
Source abstract
Abstract
Graphene/copper composite materials with excellent mechanical and electrical properties are urgently needed in many industrial fields. In this study, we successfully prepared oriented nitrogen-doped graphene-like/copper (NGL/Cu) composite materials with high strength and electrical conductivity. Structural characterization reveals that NGL with a nitrogen content of 5.95 atom % is uniformly distributed on the surface of flake copper with a good orientation. Through hot-pressing sintering, a layered structure is formed within the copper matrix. The layered structure of NGL has proven effective in load transfer and impeding dislocation slip. Following cold rolling treatment, the NGL/Cu composite material exhibited a tensile strength of 435 MPa, which is 1.94 times higher than that of the pure copper matrix. Additionally, it demonstrated a high electrical conductivity of 95.1% IACS. This high-performance graphene/copper composite material holds promising prospects for achieving enhanced electronic device performance and reliability.
