Facile Preparation of Hybrid Fluids from Ionic Liquid-Inorganic Nanoparticles:Focus on Surface Modification of the Nanoparticles

摘要

Hybrid fluids formed from inorganic nanoparticles and ionic liquids have been prepared. Although nanoparticles covalently modified with 1-methylimidazolium chloride were uniformly dispersed in water containingrnl-butyl-3-methylimidazolium chloride at first, they formed hydrophobic dispersions after potassiumrnbis {(trifluoromethyl)sulfonyl} amide was added, due to anion exchange at the surface of the nanoparticles. The concentration method needs no evaporation, centrifuging, filtration, or dialysis techniques, even if the nanoparticles were dispersed at a low level in ionic liquids.
