  • REDOX FRACTIONATION OF SINGLE-WALLED CARBON NANOTUBES
    Publication number: 20100176349
    Abstract: A method for separating fractions of single-walled carbon nanotubes includes exposing a solution containing fractions of single-walled carbon nanotubes to a reducing agent and separating the resulting reaction products. An alternate method for separating fractions of single-walled carbon nanotubes includes exposing a solution containing fractions of single-walled carbon nanotubes to an oxidizing agent and separating the resulting reaction products. A third method for separating fractions of single-walled carbon nanotubes includes exposing a solution containing fractions of substantially non-functionalized single-walled carbon nanotubes to a charge transfer complex agent and separating the resulting reaction products. These methods allow the production of single-walled carbon nanotubes of approximately 95 to 99% metallic and semiconducting types.
