摘要：

Dielectric response of (0-3) type composites, made of BaTiO3 particles with mean size of 20-30 nm and polyvinylidene fluoride was found to be determined by the response of BaTiO3 with a broad Curie point anomaly at T-C approximate to 317 K. The dielectric anomaly appears in the same temperature range where the decrease in the wai,e number of the strongest Raman band at similar to 520 cm(-1) was observed. HRTEM images revealed a core-shell structure of the BaTiO3 particles and in some grains greater than similar to 20 nm fine 180 degrees domain structure was observed.
