Abstract

A ceramic-powder polymer composite, making use of a relaxor ferroelectric polymer that has a high room-temperature dielectric constant as the matrix, is developed. The experimental data show that the dielectric constant of the composites with Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃ powders can reach more than 250 with weak temperature dependence. In addition, the composites under a proper preparation procedure exhibit a high breakdown field strength (>120 MV/m), leading to a maximum energy storage density of more than 15 J/cm³. Experimental results also indicate that the high electron irradiation does not have much effect on the dielectric behavior of Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃ powders, possibly due to the relaxor nature of the ceramic.
