以单壁碳纳米管(SWCNT)为模板，采用电沉积法制备了铜/单壁碳纳米管(SWCNT)复合材料。采用直接电沉积法制备了铜/单壁碳纳米管复合材料。采用酸性硫酸铜镀液作为碱性镀液，考察了添加剂对镀铜层形貌的影响。将聚乙二醇、氯离子(Cl-)、双(3-磺丙基)二硫化物(SPS)和贾努斯绿B(JGB)单独或联合添加作为添加剂。在不加添加剂的碱性镀液中，铜的沉积只发生在单壁碳纳米管的表面。相反，当使用至少含有聚乙二醇和氯离子的镀液时，铜不仅沉积在单壁碳纳米管的表面，而且沉积在单壁碳纳米管的内部，从而形成铜/单壁碳纳米管复合材料。在碱性镀液中加入四种添加剂(聚乙二醇、氯离子、SPS和JGB)，可显著加速铜在单壁碳纳米管薄膜中的电沉积。这种以碳纳米管薄膜为模板制备铜/碳纳米管复合材料的新方法可应用于各种金属/碳纳米管复合材料的制备。©作者(S)2017。由ECS出版。这是一篇开放获取文章，根据知识共享署名4.0许可证(CC by，http://creativecommons.org/licenses/by/4.0/)，)的条款分发，该许可证允许在任何介质中不受限制地重复使用作品，前提是正确引用原始作品。[DOI：10.1149/2.0041714]版权所有。
Copper/single-walled carbon nanotube (SWCNT) composites were fabricated by electrodeposition using a freestanding SWCNT film as a template. The SWCNT films were directly electrodeposited to form copper/SWCNT composites. An acidic copper sulfate bath was employed as a basic plating bath, and the effects of additives to the basic bath on the morphologies of copper deposits were examined. Poly(ethylene glycol), chloride ions (Cl–), bis(3-sulfopropyl)disulfide (SPS), and Janus green B (JGB) were added individually or in combination as additives. Electrodeposition of copper occurred only on the surface of the SWCNT film when using the basic plating bath without additives. In contrast, copper was deposited not only on the surface but also in the interior of the SWCNT film when using the plating baths containing at least PEG and Cl–, resulting in copper/SWCNT composites. Electrodeposition of copper inside the SWCNT film was accelerated dramatically when all four additives (PEG, Cl–, SPS, and JGB) were added to the basic bath. This novel fabrication method of copper/CNT composites using CNT films as templates can be applied to the fabrication of various types of metal/CNT composites. © The Author(s) 2017. Published by ECS.
