Study on macroscopic properties of ionic liquids originating in dynamical properties related to local structures

我们用太赫兹时域谱研究了离子液体，其微观结构由纳米尺度的结构组成，包括极性和非极性微区。我们测量了一系列离子液体/水溶液的太赫兹介电谱，从大块离子液体到大块水。我们指出，离子液体和水在微观意义上并不是均匀溶解的，而是微相分离的。

We investigated ionic liquids using terahertz time-domain spectroscopy, microscopic structures of which consist of nanometer-size structures containing polar and nonpolar microscopic domains. We measured terahertz dielectric spectra of ionic liquid/water solutions with a series of concentrations from bulk ionic liquid to bulk water. We indicated that ionic liquids and water are not uniformly dissolved in the microscopic sense but are microphase-segregated.
