摘要

Soft magnetic carbonyl iron (CI) particle-based magnetorheological (MR) fluids have been broadly used in mechanical systems due to their outstanding magnetic merits. However, serious sedimentation and agglomeration problems have been regarded as critical drawbacks during preparing and testing the CI-based MR fluids. In this study, we adopted plate-like particles of graphene oxide (GO) as a gap-filler for the CI-based MR fluid to improve its sedimentation problem. MR properties were evaluated using a rotational rheometer, and the improved dispersion characteristics were observed in the CI/GO mixture systems via a Turbiscan apparatus. To study the effectiveness of the GO additive more clearly, different weight ratios of GO in CI/GO mixture MR systems were compared.
