    摘要: Non-aqueous electrorheological fluids are described which comprise a major amount of a hydrophobic liquid phase and a minor amount of a dispersed particulate phase comprising conductive polymers selected from the group consisting of polypyrroles, polyphenylenes, polyacetylenes, polyvinylpyridines, polyvinylpyrrolidones, poly(substituted anilines), polyvinylidene halides, polyphenothiazines and polyimidazoles. The electrorheological fluids prepared in accordance with the present invention are useful in a variety of applications including flotational coupling devices such as clutches for automobiles or industrial motors, transmissions, brakes or tension control devices; and linear damping devices such as shock absorbers, engine mounts and hydraulic actuators.

    摘要: An electrorheological fluid of a particulate phase and a continuous phase of a hydrophobic liquid medium, a certain dispersed particulate phase, and a low molecular weight polar material exhibits a broad effective temperature range. The dispersed particulate phase comprises a polar solid material which is capable of exhibiting substantial electrorheological activity only in the presence of a low molecular weight polar material, and an organic semiconductor. The weight ratio of the polar solid material to the organic semiconductor is at least about 2:1.

    摘要: Non-aqueous electrorheological fluids are described which comprise a major amount of a hydrophobic liquid phase and a minor amount of a dispersed particulate phase of a polyaniline prepared by polymerizing aniline in the presence of an oxidizing agent and from about 0.1 to about 1.6 moles of an acid per mole of aniline to form an acid salt of polyaniline, and thereafter treating the acid salt with a base. The polyanilines may be prepared from aniline or from mixtures of aniline and other monomers such as pyrroles, vinyl pyridines, vinyl pyrrolidones, thiophenes, vinylidene halides, phenothiazines, imidazolines, N-phenyl-p-phenylene diamines or mixtures thereof. The electrorheological fluids prepared in accordance with the present invention are useful in a variety of applications including flotational coupling devices such as clutches for automobiles or industrial motors, transmissions, brakes or tension control devices; and linear damping devices such as shock absorbers, engine mounts and hydraulic actuators.
