| 摘要 |
A magnetorheological fluid, according to the present invention, has multilayer-structured particles formed therein by having ferromagnetic particles surrounded with polymers, and the multilayer-structured particles gain porosity by going through a foaming process, thereby decreasing the density and increasing the stability of the magnetorheological fluid, thereby enabling the marked decrease in the settling velocity thereof. The magnetorheological fluid has a millisecond (10-3 second) level response speed to a magnetic field, thereby being very fast, reversible, and simultaneously, having enhanced stability, and thus may be widely used for the development of various equipment using magnetorheological fluid. |
