Recent progress on the magnetorheological plastomers
International Journal of Smart and Nano Materials, 2015 Different from the traditional magnetorheological (MR) fluids and elastomers, the magnetic particles in the plastic MR materials are not ‘deadly’ trapped in the polymer matrix; thus, the MR plastomers exhibit higher MR effects and lower sedimentation ...
