Synthesis of rGO/CoFeO Composite and Its Magnetorheological Characteristics.

In this study, composite particles of rGO/CoFeO were synthesized using a solvothermal method to fabricate a low-density magnetorheological (MR) material with enhanced sedimentation stability. The morphology and crystallographic features of rGO/CoFeO were characterized via SEM, TEM, and XRD, and its magnetic properties were tested using VSM. The MR fluid was formulated by blending rGO/CoFeO particles into silicone oil.
