【Abstract】 The main factor to determine material performance of electrorheological fluids is the choice of their dispersion. Lithium keto aldehyde as dispersion particles of electrorheological fluid was presented. The factors that influence its molecular weight, such as reaction temperature, reaction time, catalyzer content and so on have been studied. The electrorheological fluids in this study consistes of salt of keto aldehyde particles dispersed in silicone oil. The rheological response of the electrorheological fluids was examined. The properties of electrorhelolgical fluids which include stability, temperature, rheology and dielectric constant etc. were measured and analyzed. The results indicated that the rheology of electrorheological fluids is stable in high shear strain rate.更多还原
