研究了由平均粒径为20 ~ 30 nm的batio3颗粒与聚偏氟二烯组成的（0 ~ 3）型复合材料的介电响应由batio3在TC≈317 K处具有宽居里点异常的响应决定。介电异常出现在同一温度范围内，在~ 520 cm−1处观察到最强拉曼带波数减少。HRTEM图像显示batio3颗粒为核壳结构，在大于~ 20 nm的颗粒中观察到细小的180°结构。
Abstract Dielectric response of (0–3) type composites, made of BaTiO 3 particles with mean size of 20–30 nm and polyvinylidene fluoride was found to be determined by the response of BaTiO 3 with a broad Curie point anomaly at TC ≈ 317 K. The dielectric anomaly appears in the same temperature range where the decrease in the wave number of the strongest Raman band at ∼520 cm−1 was observed. HRTEM images revealed a core-shell structure of the BaTiO 3 particles and in some grains greater than ∼20 nm fine 180° domain structure was observed.
