摘要： Titanium oxide (TiO2) particles decorated with multiwall carbon nanotubes (MCNTs) were synthesized and applied to prepare ER suspensions in this study. Compared with the bare TiO2 particles, the MCNTs decorated TiO2 particles have a rougher surface but little change in diameters. Thanks to the less severe aggregation and better dispersibility of the decorated particles, the MCNTs decorated TiO2 particles- based ER fluids present higher viscosity and higher shear stress than the bare TiO2 particles- based materials, indicating enhanced ER performance. In addition, the ER fluid containing the MCNTs decorated TiO2 particles present lower leakage current density and better anti-settling ability than that containing the bare particles. The MCNTs decorated TiO2 particlesbased ER fluids with enhanced ER performance, improved anti-sedimentation property, and lower leakage current density may be a promising ER material for practical applications.
