NONAQUEOUS SUSPENSION EXHIBITING ELECTRORHEOLOGICAL EFFECT, AND DAMPER USING SAME

摘要

Provided are a non-aqueous suspension exhibiting an electrorheological effect and a damper constructed using the non-aqueous suspension.;A non-aqueous suspension exhibiting an electrorheological effect, including a non-aqueous liquid; and organic polymer particles dispersed in the non-aqueous liquid, wherein the organic polymer particles have at least one type of ion in the inside or on the surface of the organic polymer particles, wherein when a 5 kV/mm voltage is applied between a pair of electrodes, the logarithmic value of frequency factor in Arrhenius equation for the current density (μA/cm²) flowing between the electrodes through the non-aqueous suspension is 20 or more.
