Abstract

Abstract

In order to effectively improve the dielectric properties of polymer matrix composites and consider the coexistence of high dielectric constant and low filler content, the microcapacitor structure was constructed in the barium titanate-graphene/polyvinylidene fluoride (BT-GNP/PVDF) composite system with PVDF as the matrix resin, BT and GNP as the dielectric filler and conductive filler respectively. The GNP/PVDF films and BT-GNP/PVDF composite films were prepared by solution method and hot pressing method. The results show that the BT and GNP fillers can be evenly distributed in both the BT-GNP/PVDF composite films and they are easier to form microcapacitor structure in the hot-pressing films. With the introduction of BT, the structure of the microcapacitor formed between GNP and BT is more conducive to the improvement of the dielectric constant of the BT-GNP/PVDF composite films. The dielectric constant of BT-GNP/PVDF composite films with BT content more than 50wt% are not lower than that of GNP/PVDF composites. The dielectric constant of BT-GNP/PVDF composite film with BT content of 50wt% is higher than that of the BT-GNP/PVDF composite films with BT content of 35wt%, 60wt% and 70wt%, respectively, the maximum is about 43, equivalent to 1.5 times of GNP/PVDF film with GNP content of 0.8wt%. The dielectric loss of BT-GNP/PVDF composite film with BT content of 50wt% is also smaller than other systems, the maximum value is no more than 0.09 and the minimum value is about 0.02. The conductivity of BT-GNP/PVDF composite films are in consistant change trend and there is no significant difference between them.
