摘要：

Surfactant bilayer-stabilized aqueous magnetic fluids have been characterized in terms of their magnetic properties, particle size and size distributions, and surfactant bilayer structure. Thermal analysis showed the existence of two distinct populations of surfactants on the particle surface and possible interpenetration between the tails of the primary and secondary surfactants, which was confirmed in a small angle neutron scattering study using contrast matching.
