Electrorheological elastomers (EREs) have viscoelastic properties controllable by external electric fields. For their application, it is necessary to investigate the rheological properties of EREs under various loading conditions. In this work, anisotropic EREs based on a silicone rubber with 10 wt% of PI-Na polyimide particles oriented in an electric field were first obtained. Their elastic properties were evaluated in relation to the frequency and amplitude of strain in an electric field of strength from 0 to 2 kV/mm. The elasticity of the material investigated increased by 50% when the strength of electric field raised to 1.8 kV/mm. The maximum electrorheological effect was found to be at 25°C.
