Non-ionogenic amphiphiles in aprotic ionic liquids

Abstract

Structural properties of the imidazolium ionic liquid-non-ionogenic amphiphile system are studied on the basis of the integral equation theory. The effect of the alkyl substituent lengths of cations and solvent selectivity on the features of amphiphile self-assembly is studied. The need to allow for solvent structure in constructing a theory of phase behavior of amphiphile in ionic liquid is demonstrated. The characteristic scales of structural inhomogeneities of a mixture at the stage of the self-assembly of amphiphile molecules are analyzed. Aggregation characteristics of mixture, particularly medium-field spinodal temperature are calculated, depending on amphiphile concentration.
