Paper Abstract

In this paper, electrorheological (ER) suspensions containing polypyrrole particles and castor oil were prepared. The rheological and conductive properties of these polypyrrole-based suspensions and their influencing factors, such as electric field strength, particle concentration, temperature and shear rate, were investigated as well. The experimental results show that with increasing electric field strength, particle concentration and shear rate, the shear stress of the suspension is enhanced; while with an increasing temperature, the shear stress of a suspension decreases. The conductive properties of the suspension was found to increase with an increase of electric field strength, particle concentration and temperature, but decrease with shear rate.
