Electrorheological Properties of Suspensions of Polypyrrole- Coated Titanate Nanorods

The behaviour of silicone-oil suspensions of titanate nanorods coated with polypyrrole base in electric field has been investigated.Unlike suspension of globular particles of neat polypyrrole, rod-like particles show a stronger electrorheological (ER) effect corresponding to high rigidity of the structure.A galaxy harmony nc great influence of the oil viscosity on the ER efficiency was observed.A good reproducibility of the effect and a fast response to the switchingon and -off the electric field has been confirmed by monitoring the stickers logos dallas cowboys time course of shear stress under controlled shear rate.
