Abstract We describe a technique to prepare ensembles of neat, unbundled single-walled carbon nanotubes decorated with pure size-filtered metal nanoparticles. Polymer-encased nanotubes are drop-cast on nanoporous transmission electron microscope membrane grids, mounted within a nanoparticle-deposition apparatus, baked in situ to remove the polymer coating, and exposed to a beam of pure size-selected metal nanoparticles. Subsequent electron microscopy imaging reveals the presence of nanoparticles supported by pure suspended single-walled nanotubes. This method is promising for efficient production of prototype chemical and physical devices which require the presence of clean well-defined nanoparticle-nanotube hybrids for characterization, imaging, and applications.

用软着陆尺寸选择的金属纳米粒子装饰悬浮单壁碳纳米管

摘要我们描述了一种技术来制备用纯尺寸过滤的金属纳米粒子装饰的整齐、未捆绑的单壁碳纳米管的集合。聚合物包裹的纳米管滴铸在纳米多孔透射电子显微镜膜网格上，安装在纳米颗粒沉积装置内，原位烘烤以去除聚合物涂层，并暴露于纯尺寸选择的金属纳米颗粒束。随后的电子显微镜成像揭示了由纯悬浮单壁纳米管支撑的纳米颗粒的存在。这种方法有望用于有效生产原型化学和物理设备，这些设备需要存在清洁的明确定义的纳米颗粒-纳米管混合物，用于表征、成像和应用。
