Preparation of Micron Polymer-Fe Capsulized Composites by Mechanic Milling and MR Effect of Concentrated Suspensions

Polymer-Fe capsulized composite particles with micron-size are successfully prepared by directly milling the mixture of polymer and metallic iron powder. The effects of preparation conditions is discussed in detail. In addition, the magnetorheological fluid effect of concentrated suspensions consisting of these particles, and the stability of the particles anti-sedimentation in the concentrated suspensions are simply studied.
