摘      要：Perovskite lead zirconate(PbZrOz)was synthesized in an orthorhombic form at a temperature below the Curie temperature,*** orthorhombic form is a noncentrosymmetric structure which is capable of spontaneous *** transform infrared(FTIR)spectra and X-ray diffraction(XRD)patterns confirm the siuccessful synthesis of the lead zirconate;and scanning electron microscopy(SEM)micrographs indicate that PbZrO_(3) particles are moderately dispersed in the natural rubber(NR)*** an electrical field,the particles merely act as a ferroelectric fller,which can absorb and store additional *** an electrical field,particle induced dipole motents are generated,leading to interparticle interaction and a sub-stantial increase in the storage *** a small amount of lead ziroonate part iculates present in the natural rubber matrix,at a volume fraction of 0.007306,the electrical conductivity increases dramatically by nearly two orders of magnitude at the electrical frequency of 500 kHz.
