Abstract

Using palygorskite (PAL) as template, the PAL/TiO₂/PANI nano-rods were synthesized by heterogeneous precipitation and in-situ polymerization. The synthesized PAL/TiO₂/PANI nanorods were used as a novel electrorheological (ER) fluid by mixing with silicone oil, which showed excellent ER effect. The yield stress of the PAL/TiO₂/PANI based ER fluid (15 vol%) reached 8.8 kPa under 4 kV mm⁻¹ electric field. The dynamic shear stress of the PAL/TiO₂/PANI based ER fluid could maintain a stable level in the shear rate range of 0.1–100 s⁻¹ . Furthermore, the PAL/TiO₂/PANI ER fluid exhibited excellent suspension stability.
