摘要： A homogeneous electro rheological fluid is provided. The fluid comprises a lyotropic liquid crystalline polymer dissolved in a solvent in low concentrations in a manner in which the fluid does not exhibit a liquid crystalline state. According to the homogeneous electro rheological fluid of the present invention, the problem associated with the precipitation of particles can be circumvented. Moreover, the electro rheological fluid can provide a large difference in torque before and after the application of an electric field; therefore, exhibits good electro theological properties. The electro rheological fluid according to the present invention can be used in making engine mounts, damping apparatuses, clutches, torque converters, braking systems, valves, dampers, suspensions, actuators, vibrators, ink jet printers, and the like.
