摘要：

The frequency-dependent shear viscosity of the mixtures of water with two ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate and 1-hexyl-3-methylimidazolium tetrafluoroborate, is measured at frequencies between 5 and 205 MHz. In the cases of both mixtures, the normalized spectra at different water contents reduce to single curves when they are plotted against frequency multiplied with zero-frequency shear viscosity. It indicates that the addition of water into ionic liquids reduces their shear viscosity through the promotion of structural relaxation.
