“…We suppose that the conduction loss might be attributed mainly to the conduction loss at low frequencies and this phenomenon will be discussed further in the following section. The decrease trend of the dielectric loss observed at high frequency is supposed to be resulted from the less contribution of dipoles relaxation, which is consistent with other reports [26] . It is of great help to confirm the mechanism of the dielectric behavior to conduct temperature-dependent dielectric properties measurement.…”

Abstract.Zinc oxide (ZnO) nanorods were synthesized using a modified wet chemical method. Poly(vinylidene fluoride-co-hexafluoropropylene), P(VDF-HFP), nanocomposites with different ZnO nanorods loadings were prepared via a solution blend route. Field emission scanning electron microscopic (FESEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR) were used to investigate the structure and morphology of the nanocomposites. XRD and FT-IR data indicate that the incorporation of ZnO nanorods promote the crystalline structure transformation of P(VDF-HFP). As the content of ZnO nanorods increases, the β phase structure increases while the α phase decreases. In addition, the dielectric properties of the P(VDF-HFP) and its composites were systematically studied.

“…Yang et al reported on CCTO/PVDF composites using micro-CCTO powders by hot pressing at about 200 C and under 50 MPa. 66 One may find that two CCTO-based composite systems exhibit very different dielectric constant. This is related to CCTO used.…”

0-3 dielectric composites with high dielectric constants have received great interest for various technological applications. Great achievements have been made in the development of high performance of 0-3 composites, which can be classified into dielectricdielectric (DDCs) and conductor-dielectric composites (CDCs). However, predicting the dielectric properties of a composite is still a challenging problem of both theoretical and practical importance. Here, the physical aspects of 0-3 dielectric composites are reviewed. The limitation of current understanding and new developments in the physics of dielectric properties for dielectric composites are discussed. It is indicated that the current models cannot explain well the physical aspects for the dielectric properties of 0-3 dielectric composites. For the CDCs, experimental results show that there is a need to find new equations/models to predict the percolative behavior incorporating more parameters to describe the behavior of these materials. For the DDCs, it is indicated that the dielectric loss of each constituent has to be considered, and that it plays a critical role in the determination of the dielectric response of these types of composites. The differences in the loss of the constituents can result in a higher dielectric constant than both of the constituents combined, which breaks the Wiener limits.

“…Zhong et al, found that the size of doping calcium carbonate particles have close relationship with the toughening effect to the PVC composites [14]. The dielectric constants of the PI/CCTO (CaCu 3 Ti 4 O 12 ) composites could be improved from about 100 to 10 6 , which are about 5 orders, when instead of micron CCTO particles by nanoparticles [15]. The interface layers between polyimide and silica nanocomposite will have a significant impact on mechanical properties, when the radius of silica nanocomposite filler is less than the 100 nm [16].…”
