Structural probing of clusters and gels of self-aggregated magnetic nanoparticles

Abstract

The microstructure of home-made aqueous magnetic fluids based on maghemite (γ−Fe2O3) and cobalt ferrite (CoFe2O4) nanoparticles is monitored from repulsive on the average towards attractive on the average by tuning the interparticle electrostatic repulsion through modulations of ionic strength and pH. A self-aggregation leading to sols of individual clusters and/or a thixotropic gel phase is induced. Their microstructure under finely controlled physico-chemical conditions is probed in zero field by Small Angle X-ray Scattering and Ultra-Small Angle Neutron Scattering.
