Figure 3

Dielectric and percolation properties of the MXene/PVDF membrane. (a) Schematic illustration of the dielectric effect in MXene/PVDF composite and the polarization charges distribution in the MXene/PVDF metal-insulator-metal (MIM) capacitors under the external electric field (Eext). (b) Corresponding simulation of the potential distribution on MXene flakes by COMSOL Multiphysics. (c) Dielectric permittivity of the MXene/PVDF composite versus MXene loading at various frequencies (10 Hz-10 MHz). (d) Dielectric permittivity of the MXene/PVDF composite at different loadings measured at 1 kHz. (e) Conductivity of the MXene/PVDF composite versus MXene loading at various frequencies (10 Hz-10 MHz). (f) Conductivity of the MXene/PVDF composite at different loadings measured at 1 kHz.
