ABSTRACT:
A magnetorheological (MR) fluid including magnetically soft particles suspended in a carrier solvent is disclosed. The MR fluid also includes additive particles of smaller size than the magnetically soft particles and a bridging polymer. The additive particles and polymer form a gel-like material which provides a blanket or coating around the magnetically soft particles. The MR fluids possess improved stability and redispersibility, as well as favorable mechanical properties.
