摘　　要：Copper and copper-based materials are widely used in power electronics,auto-mobiles,mechanical manufacturing and high-tech manufacturing fields such as aerospace,telecommunications and integrated circuits owing to their compre-hensive advantages in mechanical,electrical conductivity and processing prop-erties.With the rapid development of technology,many emerging technical fields have introduced more challenging requirements for the electrical conductivity of copper.This article reviews the research status of high-conductivity copper-based materials and introduces three methods to improve electrical conductivity,including purification,alloying and addition of nanocarbon materials.We sum-marise the advantages,disadvantages and future development trends of methods for improving copper conductivity.The key to producing high-conductivity copper-based materials is development of low-cost,continuous and stable processes.
