Electrorheological fluid composition comprising an electrically insulating oil and dielectric particles of polymer grafted carbon black dispersed thereon
 An electrorheological fluid composition comprises dielectric particles as a disperse-phase and an electrically insulating oil as a dispersion medium, wherein the dielectric particle has a polymer portion and an electrically conductive carbon black portion and the polymer portion is grafted on the carbon black portion. The electrorheological fluid composition shows a large change in viscosity and the small current properties under an applied electric field, and excellent fluidity and dispersion stability in an absence of an applied electric field.
