摘要

In order to obtain the high dielectric constant and low loss materials by using the two main methods for synergy,the 3-phases TiO2/(PVDF+Fe3O4)composites with the fixed Fe3O4 fraction have been prepared by using a simple blending and hot-molding technique.The dielectric measurement results show that no synergistic effect but a cancellation effect has been found here,corresponding to the decrease of dielectric constant and conductivity.The value of the relative dielectric constant dropped to the original level of polymer matrix.The reasons for the counter result are present here.It is helpful and reference for the proper choice for multiphase composite system.
