Abstract: Disclosed is an ER fluid comprising a water-soluble starch as a conductive particle and an additive to improve flow properties and to prevent precipitation of the ER fluid. The ER fluid can be widely applied to a variable attenuator which is able to control a suspension, a vibration damper and an engine mount, to a power unit such as a break and a clutch, and to various industrial fields such as an automobile and aviation industries.

Abstract: The ER fluid comprising water-soluble starch as conductive particles contains less than 5 wt % water. The ER fluid of the present invention comprises water-soluble starch as a conductive particle which is dispersed in non-conductive media. The ER fluid of the present invention exhibits a considerable ER effect, even though the amount of water contained in the ER fluid is reduced. Thus, it can be widely applicable to water-sensitive damping devices and power devices such as a suspension system, a vibration damper or an engine mount, a break, a clutch, and so forth. And it is feasible for various fields such as an automatic and an aerospace industry.
