Abstract Multilayered graphene is grown on copper (Cu) wires by chemical vapor deposition. Mechanical, chemical, thermal and electrical performances are investigated as a function of growth conditions. The graphene layer which makes a volume of approximately 0.02% of the Cu wire enables a 28–37% improvement on tensile strength and strain-to-failure. The chemical resistance of graphene grafted Cu wires increases by 1.5–3 times in nitric acid, aqua regia, and 1M ammonium persulfate etchants. The electrical resistivity of graphene grafted Cu wires remains almost constant with increasing temperature up to 175 °C, while the resistivity degradation of Cu wires without graphene starts to increase from 70 °C. We demonstrate that graphene can protect the Cu wire from thermal oxidation and chemical etchants and can effectively enhance the mechanical and electrical properties of the Cu wire.

多层石墨烯接枝铜线

摘要 通过化学气相沉积在铜 (Cu) 线上生长多层石墨烯。机械、化学、热和电性能作为生长条件的函数进行研究。石墨烯层的体积约为铜线的 0.02%，可使拉伸强度和应变失效提高 28-37%。石墨烯接枝铜线在硝酸、王水和 1M 过硫酸铵蚀刻剂中的耐化学性提高了 1.5-3 倍。随着温度升高到 175°C，石墨烯接枝铜线的电阻率几乎保持不变，而没有石墨烯的铜线的电阻率从 70°C 开始增加。
