Paper Abstract

TiO2/ZnC2O4 nanocomposites were synthesized by means of co-precipitation method. The XRD, SEM, FTIR and DTA/TG were used to determine the structure of the nanocomposites. The electrorheological (ER) activity of the suspension of TiO2/ZnC2O4 dispersed in silicone oil was investigated under a dc electric field. An excellent ER effect was found. Under 5 kV/mm external electric field, the yield stress of the TiO2/ZnC2O4 suspension can reach up to 90 kPa, and the leaking electric current density is lower than 20 μA/cm2. The yield stresses exhibit a near linear dependence on applied electric field unlike the conventional fluids. The results demonstrate that the polar molecules such as hydroxyl groups and oxalate groups adsorbed on the particles play a decisive role in determining the characteristics of the ER fluids.
