Magnetite-polyurethane (PU) shape memory polymer (SMP) composites containing 10–40vol.% magnetite have been prepared and their mechanical properties in a temperature range from 255K to 355K at vibrating frequencies of 0.1Hz, 1.0Hz and 10Hz were investigated. The damping peak at glass transition around 318K is decreased by the addition of magnetite while it becomes simultaneously broader. Also activation...
