Abstract

In this paper, we report the results on particle structure in water-based magnetic fluid (MF) using scanning probe microscope (SPM), dynamic light scattering (DLS) and small angle X-ray scattering (SAXS). The SPM analysis showed the presence of ring structures. Furthermore, the DLS measurements indicated the presence of particles as large as few hundred nanometers. The SAXS measurements suggested that the clusters are formed in water-based MF although the primary unit is similar to oil-based MF. The size and proportion of the clusters depended on the dispersion mechanism.
