摘要：

The differential capacity of a large number of liquid-liquid interfaces has been determined by impedance spectroscopy. Even in the absence of ion pairing, the interfacial capacity was always larger than predicted by Gouy-Chapman theory. These findings are explained within a simple model, in which an extended mixed-boundary layer exists at the interface, whose thickness extends over several solvent diameters.
