Title: Polyethylene-Glycol-Mediated Self-Assembly of Magnetite Nanoparticles at the Liquid/Vapor Interface

Abstract

It is shown that magnetite nanoparticles (MagNPs) grafted with polyethylene glycol (PEG) self-assemble and short-range-order as 2D films at surfaces of aqueous suspensions by manipulating salt concentrations. Synchrotron X-ray reflectivity and grazing-incidence small angle X-ray scattering studies reveal that K 2CO 3 induces the migration of the PEG-MagNPs to the liquid/vapor interface to form a Gibbs layer of monoparticle in thickness. As the salt concentration and/or nanoparticle concentration increase, the surface-adsorbed nanoparticles become more organized. And further increase in salt concentration leads to the growth of an additional incomplete nanoparticle layer contiguous to the first one at the vapor/liquid interface that remains intact.
