Title:
NONAQUEOUS SUSPENSION EXHIBITING ELECTRORHEOLOGICAL EFFECT, AND DAMPER USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/035330
Kind Code:
A1
Abstract:
Provided are a nonaqueous suspension exhibiting an electrorheological effect, and a damper which uses same. This nonaqueous suspension exhibiting an electrorheological effect is obtained by dispersing, in a nonaqueous liquid, particles comprising an organic polymer having at least one kind of ion provided therein or to the surfaces. When a voltage of 5kV/mm is applied between a pair of electrodes, the logarithmic value of the frequency factor in an Arrhenius equation expressing the current density (µA/cm2) flowing between the electrodes through the nonaqueous suspension is 20 or higher.
