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 Footcare electrorheological (ER) effect corresponding to high rigidity of the structure.A 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 time course of Stained Glass Suncatcher shear stress under controlled shear rate.
