Magnetic Rheo-SANS studies of hybrid ferrofluidic dispersions
In order to understand the magnetoviscous effect in hybrid ferrofluidic dispersion it is important to have a knowledge of flow- and field-induced microstructure formation. In conventional ferrofluids (consisting of spherical nanoparticles) strong magnetoviscous effect can be observed due to the dipolar interaction and formation of aggregates such as chains, hexagonal pseudocrystals etc. With the aim to increase shear stability, conventional ferrofluids are doped with elongated magnetic nanoparticles to form hybrid ferrofluidic dispersions. It was found that hybrid ferrofluidic dispersions reveal enhanced magnetoviscous properties, expressed as a transition from sol-like to gel-like behavior upon increasing nickel nanorod content. In this proposal, we intend to study the nanorheological behavior of such hybrid ferrofluidic dispersions by means of Rheo-SANS in applied magnetic field. The aggregate formation due to the magnetic field and shear-induced rupture of these superstructures will be investigated for several hybrid ferrofluidic dispersions with varying concentration of spherical nanoparticles.
