To improve the sedimentation stability of carbonyl iron (CI)-based magnetorheological fluid (MRF), anovel MRF with CI/MXene particles as dispersed phase was prepared. CI/MXene particles were preparedby attaching the lightweight MXene nanosheets onto the surface of CI particles (CIPs) as an additive. Themicro-morphology, crystal structure and element composition of CI/MXene particles were analyzed bySEM, XRD and XPS characterization respectively, which confirmed the successful synthesis of CI/MXene particles. CI/MXene-based MRF possessed considerable high magnetorheological (MR) effect,and the magneto-induced shear stress was up to 49 kPa. More importantly, the sedimentation ratio ofCI/MXene-based MRF was further characterized to evaluate its stability. Experimental results showedthat the sedimentation ratio of MRF increased from 75.7% to 98.0% after mixing CIPs with 3 wt%MXene nanosheets. The sedimentation ratio of CI/MXene-based MRF increased by 29.5% compared toCI-based MRF. As a result, the addition of MXene nanosheets significantly improved the sedimentationstability of MRF while maintained high MR effect.
