Aggregation of nonionic surfactants in imidazolium ionic liquids

Abstract

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; Li, Zhang et al. 2005). To this date, only little number of known non-aqueous polar solvents was found to support micelle formation. As a consequence, changing properties of a self-assembly system is limited manly to modification of the amphiphile structure. Despite extensive studies conducted on self-assembly in typical non-aqueous solvents (and their mixtures), the process is still not fully understood (Greaves and Drummond 2008).
