摘要：Polyvinylpyrrolidone (PVP)and stearic acid (SA)modified titanium oxide (TiOx )particles were synthesized by electrostatic spraying(ES)method.SEM and particle size analysis results showed that TiOx/PVP/ SA particles were regular sphere whose average size was 236.7 nm.FT-IR results showed that PVP and SA were introduced to TiOx successfully.XRD results showed that TiOx/PVP/SA particles were amorphous state. Two kind of TiOx/PVP/SA particles which were synthesized by electrostatic spraying and hydrolysis precipitation (HP)methods respectively were used to prepared electrorheological(ER)fluids in the mass fraction of 43%.The electrorheological properties were tested and the results showed that ES-TiOx/PVP/SA particles based ER fluid presents higher shear yield intensity and shear stability in comparison with HP-TiOx/PVP/SA based ER fluid.
