| Popis: | In this work, a novel two-dimensional graphene oxide-BaTiO3 (GO-BT) hybrid, via covalent bonding between animated BaTiO3 nanoparticles (BT-NH2) and graphene oxide (GO), have been prepared. Then the graphene oxide-BaTiO3 (GO-BT) hybrid is introduced into poly(vinylidene fluoride) (PVDF) matrix to obtain composites with a high-dielectric property. The microstructure and the dielectric property of the composites were investigated. The resulting composites filled with only 1 wt% GO-BT hybrids possess an excellent dielectric constant of 61 at 100 Hz, which is nearly 2.5 times that of neat PVDF. Surprisingly, the dielectric loss of the composites with 1 wt% GO-BT hybrids are as low as that of PVDF. These research results provide an effective method into the fabrication of advanced PVDF-based dielectric nanocomposites with low content of the GO-BT hybrids. |
