In this paper, ultra-long copper nanowires (CuNWs) were successfully synthesized at a large scale by hydrothermal reduction of divalent copper ion using oleylamine and oleic acid as dual ligands. The characteristic of CuNWs is hard and linear, which is clearly different from graphene nanoplatelets (GNPs) and multi-wall carbon nanotubes (MWCNTs). The thermal properties and models of silicone composites with three nanomaterials have been mainly researched. The maximum of thermal conductivity enhancement is up to 215% with only 1.0 vol.% CuNW loading, which is much higher than GNPs and MWCNTs. It is due to the ultra-long CuNWs with a length of more than 100 μm, which facilitates the formation of effective thermal-conductive networks, resulting in great enhancement of thermal conductivity.
在本文中，以油胺和油酸作为双配体，通过水热还原二价铜离子，成功地大规模合成了超长铜纳米线（CuNWs）。CuNWs的特性是坚硬且呈线性，这与石墨烯纳米片（GNPs）和多壁碳纳米管（MWCNTs）明显不同。主要研究了含有三种纳米材料的有机硅复合材料的热性能和模型。仅添加1.0体积%的CuNWs时，热导率增强的最大值高达215%，这远高于GNPs和MWCNTs。这是由于长度超过100μm的超长CuNWs有利于形成有效的热传导网络，从而导致热导率大幅提高。
