Abstract

Disclosed are electrorheological fluids including vermiculite treated with an amine salt, methods of making the same, propylene carbonate adsorbed on the solid phase, butyl benzoate added for the liquid phase, and methods of using frequency response of electrorheological fluids to vary apparent viscosity and to compensate for temperature.
