Monodisperse single-walled carbon nanotube populations and related methods for providing same

Abstract

The present teachings provide methods for providing populations of single-walled carbon nanotubes that are substantially monodisperse in terms of diameter, electronic type, and/or chirality. Also provided are single-walled carbon nanotube populations provided thereby and articles of manufacture including such populations.

We claim: 
     
         1 . A population of single-walled carbon nanotubes, wherein greater than about 90% of the population are metallic single-walled carbon nanotubes. 
     
     
         2 . The population of single-walled carbon nanotubes of  claim 1 , wherein greater than about 92% of the population are metallic single-walled carbon nanotubes. 
     
     
         3 . The population of single-walled carbon nanotubes of  claim 1 , wherein greater than about 95% of the population are metallic single-walled carbon nanotubes. 
     
     
         4 . The population of single-walled carbon nanotubes of  claim 1 , wherein greater than about 97% of the population are metallic single-walled carbon nanotubes. 
     
     
         5 . The population of single-walled carbon nanotubes of  claim 1 , wherein greater than about 99% of the population are metallic single-walled carbon nanotubes. 
     
     
         6 . The population of single-walled carbon nanotubes of  claim 1 , wherein greater than about 99.9% of the population are metallic single-walled carbon nanotubes. 
     
     
         7 . The population of single-walled carbon nanotubes of  claim 1 , wherein greater than about 90% and up to about 99.3% of the population are metallic single-walled carbon nanotubes. 
     
     
         8 . The population of  claim 1  dispersed in a liquid medium comprising two surface active components of different types. 
     
     
         9 . A population of single-walled carbon nanotubes, wherein greater than about 92% of the population are semiconducting single-walled carbon nanotubes. 
     
     
         10 . The population of single-walled carbon nanotubes of  claim 9 , wherein greater than about 95% of the population are semiconducting single-walled carbon nanotubes. 
     
     
         11 . The population of single-walled carbon nanotubes of  claim 9 , wherein greater than about 97% of the population are semiconducting single-walled carbon nanotubes. 
     
     
         12 . The population of single-walled carbon nanotubes of  claim 9 , wherein greater than about 99% of the population are semiconducting single-walled carbon nanotubes. 
     
     
         13 . The population of single-walled carbon nanotubes of  claim 9 , wherein greater than about 99.9% of the population are semiconducting single-walled carbon nanotubes. 
     
     
         14 . The population of single-walled carbon nanotubes of  claim 9 , wherein greater that about 92% and up to about 97.4% of the population are semiconducting single-walled carbon nanotubes. 
     
     
         15 . The population of  claim 9  dispersed in a liquid medium comprising two surface active components of different types.
