| Popis: | In this work, Broadband Dielectric Spectroscopy (BDS) technique is applied to investigate ((2- (3-methylimidazolyl-1-yl) -ethoxy)-carboyl)-benzoic-phthalic acid bromide (MC1) and 2-(3-methylimidazolyl-1-yl) -ethoxy-4-oxobutanoic acid bromide (MC2) ionic liquids. An impedance analyzer is used with frequencies ranging from 100mHz to 10 MHz. The real and imaginary parts of the complex permittivity, e∗(ω), and of the complex conductivity, σ∗(ω), of pure ionic liquids MC1 and MC2 and also aqueous solutions at 10%v/v, 50% v/v and 70% v/v as a function of temperature are discussed. |
