Imidazolium-based ionic liquids with a long hydrocarbon chain 1-methyl-1-ethanol-2-alkyl-imidazolium iodide ([M-E-Cn-Im] I, n = 13, 15 and 17) were used for the dispersion of DWCNTs in water.DWCNTs suspensions obtained were stable for more than a month, and no sedimentation was observed.The stability of the suspensions was investigated (measurement of optical density, zeta potential, parti-cle size, viscosity, and TEM images). Monitoring of the absorbance by UV/vis spectrophotometry for 20days… CONTINUE READING
