Semiconductorlike CaCu 3 Ti 4 O 12 ceramic powders are filled into a poly(vinylidene fluoride‐trifluoroethylene) copolymer matrix to form a flexible composite. The dielectric constant of the composites at 100 Hz reaches more than 600 at room temperature and 1200 at 70 °C, as shown in the figure. The contribution of the heterogeneous relaxation is partially responsible for the high dielectric constant observed here.
