摘要: Recent studies indicated the electrorhological (ER) effect of ER fluids with flower-like particles were more significant than those traditional sphere particles, but whether special morphology can enhance properties magnetorheological (MR) remains unclear. To address issue, cobalt (FCP) and (SCP) synthesized, two kinds MR compared. Particle characterization results indicate have difference in morphology, little crystal structure, particle size, magnetic properties. The FCP based (FCP-MRFs) present higher zero-field viscosity, field-induced yield stress, storage modulus better sedimentation stability SCP samples (SCP-MRFs). high performance FCP-MRF be attributed to particles.
