Abstract

Graphene/copper (Gr/Cu) coating-cladded Cu wires with high electrical conductivity and low surface roughness were successfully prepared from copper sulfate pentahydrate (CuSO4·5 H2O) containing Gr ranging from 0 to 2.0 g/L by direct current electrodeposition. The Gr defect density, surface morphology, surface roughness and electrical conductivity of Gr/Cu coating-cladded Cu wires were investigated. The results revealed that with the increasing Gr concentration the surface roughness and electrical conductivity of Gr/Cu coating-cladded Cu wires were enhanced simultaneously. When the Gr concentration was 1.2 g/L, Gr/Cu coating-cladded Cu wires possessed the lowest surface roughness of 4.241 μm and the highest electrical conductivity of 105.5% IACS. Compared with the counterpart without Gr, the surface roughness was reduced by 10.7%, and the electrical conductivity was increased by 5.4%, respectively. The models were developed to evaluate the surface roughness and electrical conductivity of Gr/Cu coating-cladded Cu wires.

Gr/Cu涂层包覆铜线的高导电性

以含0～2.0 Gr的五水硫酸铜（CuSO4·5H2O）为原料，成功制备了高电导率、低表面粗糙度的石墨烯/铜包覆铜线 g/L。研究了Gr/Cu涂层包覆铜线的Gr缺陷密度、表面形貌、表面粗糙度和导电性。结果表明，随着Gr浓度的增加，Gr/Cu包覆铜线的表面粗糙度和电导率同时提高。当Gr浓度为1.2时 g/L，Gr/Cu涂层包覆铜线的表面粗糙度最低，为4.241 μm，最高电导率为105.5%IACS。与不含Gr的同类产品相比，表面粗糙度分别降低了10.7%，电导率分别提高了5.4%。建立了Gr/Cu涂层包覆铜线的表面粗糙度和导电率的评估模型。

期刊介绍： The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace. Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
