摘要:
An electrorheological fluid comprising an electrically insulating liquid and acid, iodine or alcohol-treated, or iodine-treated and subsequently electrically insulating film-coated, dispersible carbonaceous particles dispersed therein has a high electrorheological effect even without lowering in a high temperature region, though it is a water-free system.

摘要:
Dispersion particles for a fluid having magnetic and electrorheological effects simultaneously, which comprise conductive ferromagnetic particles whose surfaces are coated with an electrically insulating layer and a fluid used the same. The present fluid has a larger torque induced upon application of both a magnetic field and an electric field than that in a fluid having only magnetic or electrorheological effects and higher response speed than that in a fluid having only magnetic. Furthermore, in the present fluid current difficultly passes.
摘要:
An electrorheological fluid comprising a lyotropic liquid crystalline polymer uniformly dissolved in a cyclic ketone solvent or a mixed solvent of a cyclic ketone solvent and at least one electrically insulating solvent selected from a hydrocarbon-based oil, an ester-based oil, and an ether-based oil.

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 rheological properties.
