Magnetorheology of Dimorphic Magnetorheological Suspensions Based on Iron Nanorods
Original language description
The aim of this paper is to document suitability of partial substitution of magnetic microspheres with iron nanorods to obtain dimorphic magnetorheological (MR) suspensions with comparable MR performance to conventional MR suspensions exclusively based on carbonyl iron (CI) microparticles while the sedimentation stability is considerably improved since nanoparticles play a role of steric repulsion between the CI microparticles resulting in improved stability against their rapid sedimentation. However, yield stress for dynamic applications is still maintained or even higher due to the occurring additional friction between fibers. The morphology of CI and iron nanorods was analyzed via scanning electron microscopy and transmission electron microscopy, respectively, and magnetic properties via vibrating sample magnetometry. The steady shear flow and small-amplitude dynamic oscillatory shear measurements were carried out to confirm effective MR performance. The sedimentation test showed po
