Abstract

The synthesis of stable cyclohexane magnetic fluids constituted by maghemite nanoparticles, coated by polystyrene chains (Mw=13 000) is described. α-Lithium poly(styrene) sulfonated polymer chains are adsorbed on the cationic nanoparticles of an aqueous magnetic fluid through electrostatic interactions between the anionic sulfonate group and the cationic surface. The colloidal solution obtained by dispersion of the polymer coated particles in cyclohexane is characterized by magnetic, magnetooptic and viscosity measurements. The thickness of the adsorbed polymer layer is estimated to be equal to 8 nm.
