ABSTRACT:
An electrorheological fluid including a discrete phase of the reaction product of a polymeric or monomeric crown ether and a quaternary amine, which forms non-abrasive, low density organic fibrils, in a high dielectric strength, low dielectric constant continuous phase fluid. The crown ethers are selected from both oxygen-based and sulfur-based crown ethers.
