  A number of imidazolium ionic liquids, with 2-8 carbon atoms in cation alkyl chains, and tetrafluoroborate, hexafluorophosphate, bis(trifluoromethylsulfony)imide and trifluoromethanesulfonate anions, were characterized for their ability to support micellar aggregation of nonionic surfactants in binary solutions.

  Aggregation behavior of polyoxyethylene (POE)-type nonionic surfactant Tween 20 in imidazolium ionic liquids with varying chain length and different anions, such as tetrafluoroborate, hexafluorophosphate, bis(trifluoromethanesulfonyl)imide, and trifluoromethanesulfonate, was investigated by means of surface tension, conductivity and dynamic light scattering measurements. The role of the chain length, anion size as well as interactions...

  - Rok 2013

  Micellar aggregation of surfactants in aqueous solutions has been described in terms of the balance between dispersive interactions of the hydrocarbon part of the amphiphilic molecule, and the hydration and electrostatic repulsive effects of hydrophilic head group. Changing the interactions by replacing water with another polar solvent, such as amides or glycols, has been studied to a smaller extent (Singh, Saleem et al. 1980;...
