摘要：DCs composed by dielectric particles and elastomer matrix present electric field dependent deformation. Viscoelasticity dominates their electric field response, which has to be considered in their applications. Although the influence of strain amplitude and oscillation frequency on the viscoelasticity of DCs has been investigated, the effect of electric field has been seldom studied. In this study, DCs were prepared by dispersing TiO(2)particles with different concentrations and different distributions within silicone rubbers. The areal strain and the storage modulus of the DCs under different electric fields were tested. The results indicated the electric field has significant influence on the storage modulus of the DCs. Such an electric field dependent storage modulus is more significant for the DCs with higher particle fraction, or with aligned distributed particles. The enhanced electrostatic interaction between the adjacent particles by applying electric field is responsible for the phenomena.
