Separation of metallic single-walled carbon nanotubes using various amines

Separation of metallic single-walled carbon nanotubes using various amines

Separation of metallic single‐walled carbon nanotubes (m‐SWNTs) using various amines in different concentrations was investigated. The SWNTs dispersions were characterized with Vis–NIR and Raman spectrometers. The proportion of m‐SWNTs toward semiconducting SWNTs increased with an increase of concen...

Zusammenfassung:Separation of metallic single‐walled carbon nanotubes (m‐SWNTs) using various amines in different concentrations was investigated. The SWNTs dispersions were characterized with Vis–NIR and Raman spectrometers. The proportion of m‐SWNTs toward semiconducting SWNTs increased with an increase of concentration of amines. SWNTs thin films were prepared from the SWNTs dispersion. The sheet resistance of SWNTs films decreased with an increase of proportion of m‐SWNTs.
