Abstract
Electrorheological ER fluid typically composed of polarizable particles and an insulating liquid is a kind of smart materials which can be characterized by a reversible change from a liquidlike to a solidlike state without or with an electric field 1 2 3 4 5 6 7 8 9 along with its magnetically analogous magnetorheological suspensions under an external magnetic field 10 11 12 Rheological properties of this ER material such as shear stress and shear viscosity are also altered and tuned according to the electric field Therefore many investigators put a focus on this material and dedicate to their potential applications 13 14Recently Cheng et al 15 reported a new type of anhydrous ER fluid prepared by dispersing nanocomposite particles PPy/MCM41 of conducting polypyrrole PPy confined in mesoporous silica MCM41 in silicone oil This ER material was synthesized via a polymerization of pyrrole which was introduced to the MCM41 channels prior to the
