Popis: The dielectric properties, elastic modulus, and electromechanical responses of dielectric elastomers (DEs) consisting of silicone rubber and carbon black (CB) incorporated with BaTiO3 (BT) were studied. When compared with single filler/rubber composites, the resulting three-component nanocomposites yielded very abnormal phenomena. They might be attributed to the interactions between the two kinds of fillers. The increase in concentration of CB (BT) would play a destructive role to the network structure formed by BT (CB) particles. The maximum electromechanical strain of the nanocomposites achieved at mass fraction mCB = 0.03 and mBT = 0.06. The resultant electromechanical strain would be attributed to the large dielectric permittivity in the three-component nanocomposites, in which the BT particles themselves have a high dielectric permittivity and the electrical networks of CB particles have a contribution on the increase in dielectric permittivity of the three-component nanocomposites. © 2012 Wiley Periodicals, Inc.
