- Abstract
In this work, P(VDF-TrFE)-based nanocomposites with high dielectric constant were fabricated by using MXene as a two-dimensional (2-D) filler. The produced nanocomposites were flexible and exhibit a low percolation threshold of 11.96 wt.% while their dielectric constant exceeds 2000 at a frequency of 100 Hz. P(VDF-TrFE)/MXene dielectric nanocomposites with 10 wt.% of 2-D filler exhibit a high dielectric constant of more than 1500 at 100 Hz associated with a dielectric loss of 0.8, which is much smaller than other composites that contain conductive fillers and exhibit a similar dielectric constant. When a very small amount (less than 1.0 wt.%) of MXene filler was used, the energy storage performances of these composites was slightly increased with the filler content due to its participation in polarization at a high electric field. The results indicate that 2-D MXenes are promising candidates for fabrication of high-performance dielectric composites with conductive fillers.
