ELECTRORHEOLOGICAL FLUIDS CONTAINING ELECTRONICALLY CONDUCTIVE POLYMERS

摘要

2594R/B Title: ELECTRORHEOLOGICAL FLUIDS CONTAINING ELECTRONI CALLY CONDUCTIYE POLYMERS 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 applicationsincluding 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.
