Abstract

An electrorheology (ER) fluid system, BaTiO 3 single crystal/silicone oil, was used to investigate the ER mechanism through measuring the frequency dependence of the ER effect. The shear stress was found to increase sharply with frequency below 100 Hz and reached saturated values quickly at high frequency. This phenomena was explained in terms of the mismatch of the permittivity between particles and the fluid. The results reveal that the total ER effect is the sum of interfacial and volume polarizations.
