摘要：

Composite magnetic particles (CMP) with carbonyl iron (CI) core and poly (methyl methacrylate) shell were prepared by an in-situ dispersion polymerization method via surface treated CI with acrylic acid. These CMP were adopted as dispersed phase of magnetorheological (MR) fluids, and has better MR fluids characteristics than fluid with Cl alone as they have severe sedimentation and poor dispersion quality. Flow properties of the MR fluids were analyzed via a rotational rheometer equipped with a magnetic field supplier in parallel plate geometry.
