开发了一种大气压等离子体系统，并将其用于处理碳纳米管组件，生成了碳-锌混合结构。该系统集成到浮动催化剂化学气相沉积炉中，用于合成碳纳米管的宏观组件，从而实现在线、连续和单步生产纳米复合材料。材料是以纳米颗粒的形式从牺牲的锌丝中沉积出来的，可以在单个碳纳米管形成时覆盖在它们的表面。此外，研究还发现，与可比的合成后沉积相比，沉积的材料更深入地渗透到碳纳米管基质中，通过厚度改善了材料的均匀性。从而论证了一种金属基涂层和碳纳米管的一步合成工艺，为常压等离子体制备金属-碳纳米管复合材料的规模化生产奠定了基础。
An atmospheric‐pressure plasma system is developed and is used to treat carbon nanotube assemblies, producing a hybrid carbon‐zinc structure. This system is integrated into a floating‐catalyst chemical vapor deposition furnace used for the synthesis of macroscopic assemblies of carbon nanotubes to allow for the in‐line, continuous, and single‐step production of nano‐composite materials. Material is deposited from a sacrificial zinc wire in the form of nanoparticles and can coat the surface of the individual carbon nanotubes as they form. Additionally, it is found that the deposited materials penetrate further into the carbon nanotube matrix than a comparable post‐synthesis deposition, improving the uniformity of the material through the thickness. Thus, a single‐step metal‐based coating and carbon nanotube synthesis process which can form the basis of production scale manufacturing of metal‐carbon nanotube composite materials with an atmospheric‐pressure plasma system are demonstrated.
