The wormlike micelles formed by surface active N-alkyl-N-methylpyrrolidinium bromide ionic liquids (ILs) have been investigated in aqueous solution. The typical rheological parameters and the viscoelastic properties of wormlike micelles were characterized by rheological measurements and cryogenic-transmission electron microscopy (cryo-TEM). The typical rheological parameters were further evaluated by Maxwell model and the viscoelastic properties were discussed based on the living polymer model. Cryo-TEM images confirmed the formation of wormlike micelles in aqueous solution. The effect of the hydrocarbon chain length of the ILs on the wormlike micelles formation was also studied.
