我们提出了一种基于静电力定向组装的纳米颗粒装饰单壁和多壁碳纳米管的有效气相方法。我们发现，除了固有的纳米颗粒尺寸选择外，在组装过程中还可以控制纳米颗粒对接在纳米管上的堆积密度和最终尺寸分布。我们的方法实现了纳米颗粒在纳米管上的原位涂层。由于静电力固有的与材料无关的性质，利用这种新技术可以生产出各种组成的纳米颗粒-纳米管结构。这些新颖的结构将为探索纳米科学、纳米技术和生物技术提供新的机会。
We present an efficient gas-phase route to decorate both single-walled and multiwalled carbon nanotubes with nanoparticles based on electrostatic force directed assembly. We show that, in addition to an intrinsic nanoparticle size selection, the packing density and the final size distribution of nanoparticles docking on nanotubes can be controlled during the assembly process. Our method enables in situ coating of nanotubes with nanoparticles. Due to the inherent material-independent nature of the electrostatic force, various compositions of such nanoparticle-nanotube structures can be produced using this new technique. These novel structures will enable new opportunities for exploring nanoscience, nanotechnology, and biotechnology.
