AbstractHere, we report the fabrication of electrostatic fractional capacitors based on two-dimensional Ti3C2 MXene/vinylidene fluoride–trifluoroethylene–chlorofluoroethylene terpolymer [P(VDF-TrFE-CFE)] composites. The bandwidth of MXene-based fractional capacitors varies between 200 kHz and 2 MHz, while the phase angle varies less than ±2°. Additionally, the constant phase angle of the MXene/P(VDF-TrFE-CFE) can be precisely tuned from −67° to −34° by varying the volume ratio of MXene nanosheets in the polymer matrix. The results presented in this work demonstrate the potential of MXene/P(VDF-TrFE-CFE) composites as solid-state electrostatic fractional capacitors.
