Enhancement of Dispersion Stability of Carbon Nanotube in Solvents

Abstract:

Dispersion stability of carbon nanotubes (CNTs) is a challenging issue in the preparation of nanocomposites. This paper reports the enhancement of dispersion stability of multiwall carbon nanotubes (MWCNTs) in four solvents using two surfactants and four polymeric dispersants. The dispersion stability of MWCNTs, in term of Instability Index, was characterized by an accelerated stability analyser. The two polymeric dispersants with ionic anchoring groups and solvent-compatible chains showed the best dispersion stability as they provide polar anchoring and steric barrier which enhance the dispersion stabilisation of MWCNTs in various solvents.
