    Dispersing single-walled carbon nanotubes in ionic liquids: a quantitative analysis
    (Royal Society of Chemistry, 2013-08-15) Hameed, N; Church, JS; Salim, NV; Hanley, TL; Amini, A; Fox, BL
    The efficiency of various ionic liquids, specifically the 1-butyl-3-methylimidazolium tetrafluoroborate, hexafluorophosphate, chloride and dicyanamide salts, in dispersing single walled carbon nanotubes has been examined. The SWCNTs were dispersed in the ILs at varying concentrations by grinding. All of the ILs were found to be effective dispersants for nanotubes and quantitative evidences including X-ray scattering, Raman spectroscopy and UV-visible spectroscopy unambiguously showed that BMIM[BF4] is the most efficient IL while BMIM[DCA] is the least effective IL. A quantitative analysis of the interactions between SWCNTs and ionic liquids by analyzing their scattering and spectral features is put forth.© 2013, The Royal Society of Chemistry.
