High-purity single-walled carbon nanotubes include:
High-purity single-walled carbon nanotubes CNT100,
Low purity single-walled carbon nanotubes CNT101.
Hydroxylated single-walled carbon nanotubes CNT200 (-OH),
Carboxylated SWNT CNT300 (-COOH),
Truncated SWNT CNT400,
Hydroxylated short single-walled carbon nanotubes CNT500 (-OH),
Carboxylated SWNT CNT600 (-COOH).
Hydroxyl and carboxyl groups of single-walled carbon nanotubes are at different temperatures and different concentrations of H2SO4 solution prepared by KMnO4 oxidation.
Short single-walled carbon nanotubes obtained by the chemical truncated.
