摘要
以硼氢化钠为还原剂、硫酸铜为氧化剂,并以乙二胺为络合剂,采用液相还原法制备了纳米铜线.采用SEM和XRD对所制备的纳米铜线进行了表征.结果表明:在强还原剂硼氢化钠和络合剂乙二胺的作用下,所制备的纳米铜是不含其他氧化物的纯铜;探讨了络合剂和还原剂用量对纳米铜线性能的影响,结果表明:当乙二胺用量为5mL,硼氢化钠用量为20.0mL时,所制备的纳米铜线具有均一的线型形貌和良好的分散性及防氧化性,电阻测试结果表明,此时铜线的表面电阻为10.5Ω/□.
Using sodium borohydride as reducing agent,copper sulfate as an oxidant and ethylenediamine as complexing agents,nano copper wires were prepared by liquid phase reduction method and characterized by SEM and XRD.The results showed that nano copper was pure copper without any other oxides under the strong reducing agent and complexing agent.The effects of different amounts of both complexing agents and reducing agents on the properties of nano-copper wire were also discussed.The results showed that the nano copper wires had line-type morphology,good dispersion and oxidation resistance when the ethylenediamine was 5mL and sodium borohydride was 20.0mL.The resistance test results showed that the surface resistance of the copper wire at this time was 10.5Ω/□.
