Selective and Scalable Chemical Removal of Thin Single-Walled Carbon Nanotubes from their Mixtures with Double-Walled Carbon Nanotubes

Single - Walled 4 . Single - Walled Carbon Nanotubes

Single-walled carbon nanotubes (SWCNTs) are hollow, long cylinders with extremely large aspect ratios, made of one atomic sheet of carbon atoms in a honeycomb lattice. They possess extraordinary thermal, mechanical, and electrical properties and are considered as one of the most promising nanomaterials for applications and basic research. This chapter describes the structural, electronic, vibra...

Chemical Detection Using Single - Walled Carbon Nanotubes

We have developed electronic devices and sensors that use two-dimensional random networks of SWNTs as the active electronic material [1]. Such network devices display the aggregate properties of many randomly distributed SWNTs and can be processed into devices of arbitrary size using conventional microfabrication technology. We report here on the results of our efforts to develop chemical senso...

Cutting single-walled carbon nanotubes.

A two-step process is utilized for cutting single-walled carbon nanotubes (SWNTs). The first step requires the breakage of carbon-carbon bonds in the lattice while the second step is aimed at etching at these damage sites to create short, cut nanotubes. To achieve monodisperse lengths from any cutting strategy requires control of both steps. Room-temperature piranha and ammonium persulfate solu...
