Broadband dielectric response of the ionic liquid N-methyl-N-ethylpyrrolidinium dicyanamide

Zusammenfassung

Dielectric relaxation measurements as a function of temperature, and of concentration in a non- coordinating solvent, the first reported for an ionic liquid, indicate a crossover in the relaxation mechanism due to varying levels of ion aggregation and the interplay of formation kinetics and relaxation dynamics of associates.
