Abstract
A complex mesoscopic organization is observed in systems containing ethylammonium nitrate (EAN) and two nonamphiphilic compounds, using wide and small angle X-ray scattering and molecular dynamics simulations. The macroscopically homogeneous mixtures exhibit a separation where an ionic liquid-rich region is percolating a molecular liquid-rich one, but no unmixing is observed. This effect was already reported in EAN-alcohol mixtures, but the models proposed so far cannot explain this behavior for a nonamphiphilic compound.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
