Homogeneous electrorheological fluid.

摘要

[Purpose] To provide a homogenous electrorheological fluid free from the problem of particles sedimentation.

[Structure] An electrorheological fluid comprising, as a main component, a liquid crystal compound comprising a flexible molecular chain having at least two liquid crystal substances bonded thereto.

[Effect] Being free from the problem of sedimentation of particles and therefore, it can be applied with stability for prolonged period of time to novel compact actuators handled with electric control such as valve, clutch, brake and torque convertor.
