Effects of BaTiO ₃ on dielectric behavior of BaTiO ₃ @RGO-polyvinylidene fluoride composites

This study focused on fabricating three types of BaTiO3@reduced graphene oxide (BT@RGO) hybrids with varying sizes of BT particles and investigating their impact on the dielectric behavior of BT@RGO/PVDF composites. The results highlight the significant role of BT@RGO hybrid morphology in determining the dielectric properties of the composites. The incorporation of morphology-controllable BT@RGO hybrids into the polymer matrix proves to be an effective approach for achieving composites with high dielectric constant. This research offers a valuable design strategy centered around controlling graphene morphology, which holds great potential for a wide range of applications in electromagnetic shielding, dielectric capacitors, etc.
