Ethanol is a strong solvent for DMIC–CNT bonding, thus the bound DMIC on the CNTs surface was completely washed as presented by the curve 1.Water is considered as the weaker solvent for the DMIC–CNT bonding, as a result the weight fraction of DMIC WDMIC detected in the water-washed mixture is 15% (curve 2) that evidences the bonding of DMIC to CNT surface
