Novel ferroelectric polymer composites with high dielectric constants

A very simple blending and hot-molding technique has been used to prepare novel ferroelectric polymer composites of poly(vinylidene fluoride) (PVDF) and Ni (see Figure) with a high dielectric constant of weak frequency and temperature-dependence. The polymer composites are flexible and of low dielectric loss. The electrical behavior observed in such composites can be described well using percolation theory.
