Abstract: The electroviscous fluid is a suspension composed of a finely divided dielectric solid dispersed in an electrically nonconductive oil. The viscosity of the fluid increases swiftly and reversibly under an influence of electric field applied thereto and the fluid turns to a state of plastic or solid when the influence is sufficiently strong. The electroviscous fluid of the present invention comprises 1- 60% by weight of a dispersed phase of carbonaceous particulates having average particle size of 0.01-100 micrometer, and 99-40% by weight of a continuous liquid phase of an electric insulating oil having a viscosity of 0.65-500 centistokes at room temperature. The electroviscous fluid exhibits an excellent electroviscous effect even at a high temperature with a low electric power consumption together with maintaining the improved electroviscous effect for a long period of time.

Abstract: A powder having good oxidation resistance and controlled electrical properties is obtained by dispersing minute particulates in a matrix phase to form composite particles. The minute particulates may be distributed uniformly, or non-uniformly such that the particulates are dense near the particle surface and sparse near the centre or vice versa. The minute particulates have a moderate conductivity of from 10 to 10 Scm , and the matrix phase has a low conductivity of up to 1/10 of that of the particulates. The powder can be dispersed in an insulating oily medium to form an electrorheological fluid.
