Abstrakt: | Title: Rheological properties of magnetorheological suspensions based on core-shell structured polyaniline-coated carbonyl iron particles Sedimentation caused by large density of suspended particles used in magnetorheological fluids is a significant obstacle for their wider application. In the present article, core-shell structured carbonyl iron-polyaniline particles in silicone oil were used as magnetorheological suspension with enhanced dispersion stability. Bare carbonyl iron particles were suspended in silicone oil to create model magnetorheological suspensions of different loading. For magnetorheological suspension of polyaniline-coated particles the results show a decrease in the base viscosity. Moreover, the change of viscoelastic properties of magnetorheological suspensions in the small-strain oscillatory shear flow as a function of the strain amplitude, frequency and the magnetic flux density was also investigated. | ||||||||||
