Abstract
A homogeneous electrorheological fluid is disclosed, which mainly comprises a liquid crystal compound in which a plurality of liquid crystal groups are bonded to a molecular chain either directly or via a spacer, or comprises a lyotropic liquid crystal comprising a solute and a solvent. The electrorheological fluid exhibits higher electrorheological effects as well as high response rate and low power driving properties while being free from sedimentation or flocculation.
