Abstract
The dispersion stability of carbonyl iron (CI)-based magnetorheological (MR) fluid was improved by coating soft magnetic CI particles with an environmentally benign biopolymer of xanthan gum to reduce the density gap between the medium oil and dispersed particles. The sedimentation test of the MR fluid showed that the xanthan gum/CI composite particles improved the sedimentation drawback of the pristine CIbasedMR fluid. The rheological properties of theMRfluidwere also examined using a rotational rheometer to observe the typical MR characteristics, such as yield stress and shear viscosity.
