Effect of electric fields on structure of ferrofluids at the solid interface
The reproducible development of functional nanomaterials with pre-defined properties is an essential need in different areas. In this context, magnetic-responsive materials play an important role as they can be tuned by magnetic fields. Electric fields, similar to magnetic fields, could be also a driving force inducing the assembling of magnetic nanoparticles in the bulk and at the interface. Recently it was shown that MNPs in ferrofluids can aggregate under external electric fields and according to the proposed theoretical model, it was shown that the process depends on the particles size, dielectric constant of the solvent and MNPs, temperature, and concentration among others. By using neutron reflectometry we propose to investigate NPs assembly on planar interfaces depending on particles diameter and also dielectric constant of the solvent, when an external electric field is applied to the interface. The evolution of the interface structure under external field will be traced by analyzing changes in the scattering length density depth profiles derived from neutron reflectivity curves.
