Tuning the colloidal stability in ionic liquids by controlling the nanoparticles/liquid interface

To shed light on the origin of colloidal stability in ionic liquids, we focus on a model colloidal system (maghemite nanoparticles) in which surface charge and counterion nature can be controlled at will. We thus evidence the crucial role of interfacial features on dispersion quality in a standard ionic liquid, ethylammonium nitrate.
