一种非常简单的共混和热成型技术已被用于制备聚偏氟乙烯（PVDF）和镍（见图）的新型铁电聚合物复合材料，具有弱频率和温度依赖性的高介电常数。该聚合物复合材料是柔性的并且具有低介电损耗。在这种复合材料中观察到的电行为可以很好地描述使用逾渗理论。
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.
