Behavior of multiwalled carbon nanotubes functionalized with sulfo groups in aqueous salt solutions

Nanotechnologies in Russia volume 7, pages 629–634 (2012)Cite this article

Abstract

The functionalization of multiwalled carbon nanotubes (MWCNTs) with sulfanilic acid through the diazotization reaction, which yielded the covalent bonding of sulfo groups to the nanotube surfaces, was performed. Stable aqueous nanotube dispersions were obtained. The sizes of functionalized nanotubes in aqueous salt and salt-free solutions and their hydrodynamic characteristics were measured by dynamic light scattering. The data were compared with the data of scanning electron microscopy.
