The enhancement in dielectric properties for PVDF based composites due to the incorporation of 2D TiO2 nanobelt containing small amount of MWCNTs

Film capacitors can be used as energy storage for fast storage and release energy, but the low energy density limits their applications. In our previous study, we have demonstrated that a small amount of 2D titanium dioxide (TiO2) nanobelts in PVDF could significantly enhance the energy density of these composite films. In order to increase the dielectric constant and energy density of these composites, multi-walled carbon nanotubes (MWCNTs) are...
