Abstract

Effects of ferroelectric BaTiO₃ particles were investigated on the dielectric behavior of BaTiO₃-Ni-polymethyl methacrylate composites fabricated by a two-step mixing and hot-molding method. The percolation power law in the smearing region was employed to explain the experimental results. The composites exhibit the dependence of the dielectric constant, dielectric loss, and percolation threshold on the concentration and particle size of BaTiO₃. The results suggest that BaTiO₃ particles play an important role in increasing the percolation threshold and the smearing region as well as the dielectric constant of BaTiO₃-Ni- polymethyl methacrylate composites.
