Separation and purification of functionalised water-soluble multi-walled carbon nanotubes by flow field-flow fractionation

Water-soluble, functionalised multi-walled carbon nanotubes (MWNT) have been separated and purified from amorphous material through direct flow field-flow fractionation. MWNT subpopulations of relatively homogeneous, different length were obtained by collecting fractions of the raw, highly polydispe...

Zusammenfassung:Water-soluble, functionalised multi-walled carbon nanotubes (MWNT) have been separated and purified from amorphous material through direct flow field-flow fractionation. MWNT subpopulations of relatively homogeneous, different length were obtained by collecting fractions of the raw, highly polydispersed (200–5000 nm) functionalised MWNT sample.
