LOW VISCOSITY MAGNETORHEOLOGICAL MATERIALS

摘要

A magnetorheological material containing a particle component and a carrier fluid having a change in viscosity per degree temperature ( DELTA eta / DELTA T ratio) less than or equal to about 9.0 centipoise/ DEG C over the temperature range of 25 DEG C to -40 DEG C. The magnetorheological material exhibits a substantial magnetorheological effect with a minimal variation in mechanical properties with respect to changes in temperature. The magnetorheological material is advantageous in that it provides for the design of devices that are smaller, more efficient and consume less power.
