The Colloidal Stability of Magnetic Nanoparticles in Ionic Liquids

Abstract

During the first stage of the project we initially prepared a quantity of ionic liquid ferrofluid (ILFF) based on ethyl ammonium nitrate (EAN) for evaluation by the team at Michigan Tech. This ILFF proved to be too hydrophilic, too high in viscosity and lacking in physical robustness. As a consequence we prepared an ILFF based on EMIM-NTf2, which overcame these deficiencies. This required us to overcome the difficulties involved in taking a ferrofluid that was prepared and electrostatically stabilized in water and sterically stabilize it in a hydrophobic ionic liquid (IL). This ILFF performed well in tests done at Michigan Tech and is undergoing evaluation at the Air Force Research Laboratory at Kirtland AFB.
