I can used various solvents to get the uniform dispersion . But unfortunately I was totally confused to find which one is better after all I want to know why ethanol act as a good solvent when compare with others.
Dear Rajiv :
The CNT come in solvophobic interaction. If CNT come into water, the hydrophobic interaction. Hydrophobic interaction can be divided into the amount of mole of the CNT / isothermal compressibility of the solvent. The isothermal compressibility of water 45.8, ethyl alcohol and 110 x 10-11 Pa-1. Consequently, the CNT will be harder to aggregate in water and in alcohol weaker.
Best regards.
there is no chemical reaction.
DMF would be a compatible solvent for CNT for good dispersion. Suspect both ethanol and DMF are not well compatible with PVDF, i.e. PVDF will stick together instead of mixing with the solvents.
