Abstract

Methods are disclosed for dispersing nanoparticles in solvents, involving the use of a cationic species and an anionic species, where at least one of the ionic species is soluble in the nonpolar solvent and the other ionic species has a relatively strong affinity for the surface of the nanoparticles. The cationic species and the anionic species together form a cluster of ion pairs shielding the nanoparticles and enhancing their dispersibility in the nonpolar solvent.
