The aggregation behavior of ionic liquids into micelle was studied.It was found that the micellization of ionic liquids was governed by its side-chain length
head structure and anion species
which could be promoted by increasing hydrophobicity
such as a long side-chain length
a hydrophobic anion or C2-methylated head.The side-chain length played the most active role in comparison with head group and anion.The micellization of ionic liquids would be weakened with increasing temperature.
