By combining a solution cast and a hot-press process, a process to prepare uniform metal-polymer nanocomposites is introduced. It is confirmed using two composite systems: nanosized Ni particles embedded into P(VDF-TrFE) 70/30 mol. % and P(VDF-CTFE) 88/12 mol. % copolymer, respectively. Composites with 0 vol. %–60 vol. % of Ni nanoparticles are studied. The dielectric property of each composite is characterized over a frequency range from 100 Hz to 1 MHz. The results show that two nanocomposite systems show very similar percolation behavior with a high percolation threshold (>55 vol. %) and exhibit a high dielectric constant (∼1000 at 100 Hz).
