Quasi-Langmuir–Blodgett thin film deposition of carbon nanotubes

The nanotubes were then filtered, rinsed, and washed with water until a neutral pH was obtained and then dried in a vacuum oven. The purified nanotubes were ultrasonically dispersed for 30 min in 10:1 ratio of 1,2-dimethylbenzene~ortho-xylene! and 1,2-dichlorobenzene. The nanotube concentration in so- lution was '3 mg/L.

Potential applications of carbon nanotubes - Wikipedia

Potential applications of carbon nanotubes. Carbon nanotubes (CNTs) are cylinders of one or more layers of graphene (lattice). Diameters of single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) are typically 0.8 to 2 nm and 5 to 20 nm, respectively, although MWNT diameters can exceed 100 nm.
