Abstract
An electrorheological material comprising a carrier fluid and an atomically polarizable particle component. The atomically polarizable particle component has a crystalline lattice structure which allows atoms to shift position with respect to each other in response to the application of an electric field. The electrorheological materials are subjected to an alternating current electric field at a frequency of at least 500 Hz. The materials exhibit substantial electrorheological activity over a broad temperature range.
Claims13
An electrorheological material comprising from about 5 to 50 percent by volume of an atomically polarizable particle, from about 50 to 95 percent by volume of an electrically insulating liquid as a carrier fluid, and from about 0.1 to 10 percent by weight, relative to the weight of the atomically polarizable particle, of a particle-bound dispersing agent selected from the group consisting of titanate, zirconate, and aluminate coupling agents, and combinations thereof.
