dc.description.abstract	Magnetically active particles of carbonyl iron/polypyrrole (CI/PPy) with core-shell microstructure were prepared in order to improve suspension stability of the magnetorheological (MR) suspensions which represents a significant obstacle for wider commercial applications of these smart systems. Morphology and magnetic properties were observed via scanning electron microscopy and vibrating sample magnetometry, respectively. The viscoelastic performance of the synthesized core-shell particles based MR suspensions was examined as a function of external magnetic field intensity and temperature in the small-strain oscillatory shear mode using a rotational rheometer. Furthermore, the PPy coating was found to play an important role in the dispersed particles-suspending medium interactions and, thus, enhanced suspension stability.	en
