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.

在这项工作中，通过动画的BaTiO ₃纳米粒子（BT-NH ₂）和氧化石墨烯（GO）之间的共价键合，制备了一种新型的二维氧化石墨烯-BaTiO ₃（GO-BT）杂化物。然后氧化石墨烯-BaTiO ₃将（GO-BT）杂化体引入聚偏二氟乙烯（PVDF）基体中，以获得具有高介电性能的复合材料。研究了复合材料的微观结构和介电性能。仅填充了1 wt％GO-BT杂化物的所得复合材料在100 Hz时具有优异的介电常数61，几乎是纯PVDF的2.5倍。出乎意料的是，具有1重量％的GO-BT杂化物的复合材料的介电损耗与PVDF的介电损耗一样低。这些研究结果提供了一种有效的方法来制造具有低含量GO-BT杂化体的先进的基于PVDF的介电纳米复合材料。
