2D conductive MOF modified MXene nanosheets for poly (vinylidene fluoride) nanocomposite with high permittivity

摘要

High permittivity nanocomposites have recently received extensive attention for their potential applications in energy storage and flexible electronics. In this paper, 2D conductive MOF Ni-3(HHTP)(2) was modified onto the MXene nanosheets for fabricating high permittivity poly (vinylidene fluoride) (PVDF) nancomposites with low dielectric loss. The SEM, TEM and XRD results confirm the Ni-3(HHTP)(2) MOF was grafted on MXene nanosheets successfully. The MOF-MXene/PVDF nanocomposite exhibits a high permittivity of 530 with dielectric loss of 0.49 at 4.76 wt% under 1 kHz.
