Synthesized smectite particles have been dispersed in methylphenyl silicon oil. The prepared fluid is stable in a gravitational field. The viscosity of this fluid under electric field has been investigated by many parameters as follows, smectite content in silicon oil, shear rate, electric field strength, frequency of electric field or DC field, temperature of fluid, frequency on viscoelasticity, response time, stability and durability, and so on. The shear stress and current density have increased almost in proportion to a square of electric field strength. The dynamic modulus and dynamic loss change much more in the fluid dispersing lower smectite concentration by applying electric field. For the durability of fluid the viscosity is almost same for several hours under 2kV/mm. This fluid is expected to use in the damper, actuators and so on.
