摘要：

Electrorheological (ER) properties of colloidal suspensions composed of silica particles in different type of oils were investigated under DC electric field. Silica particles were prepared through the sol-gel method by hydrolyze of tetraethylorthosilicate (TEOS). Different silica powders were prepared by adding metallic cations (Co2+ or Zr4+) in order to study their effect on the ER behaviour. The powders microstructures were characterized by XRD, FT-IR, TGA and SEM. The suspension with higher ER response was tested in an automotive damper instead of classic hydraulic oil.
