Mesoscale aggregation has been observed in many ionic liquid systems including binary mixtures. We recently investigated a series of binary mixtures of pyrrolidinium ionic liquids with the NTf2- anion using broadband dielectric spectroscopy, differential scanning calorimetry, and X-ray scattering. We found that by combining pyrrolidinium ionic liquids with propyl and decyl chains the melting point of the mixtures were reduced and the static permittivity was increased due to changes in the arrangement of polar and non-polar aggregates in the bulk liquid structure.
