Abstract Polymer/conductive ceramic composites with high dielectric constant have become research hotspot of dielectric capacitor materials. However, the conductivity and dielectric loss increase when high dielectric constant is achieved. In order to reconcile high dielectric constant and low dielectric loss, in this study, poly(vinylidene fluoride) (PVDF)/chromium carbide (Cr2C3)/montmorillonite (MMT) ternary composite films were prepared by solution cast. Dielectric response based on interfacial polarization was improved and dielectric constant of composites was increased. MMT ceramic was used to suppress interface leakage current. Compared with PVDF/Cr2C3 composites, the conductivity and dielectric loss of ternary composites were reduced.

摘要 具有高介电常数的聚合物/导电陶瓷复合材料已成为介电电容器材料的研究热点。然而，当达到高介电常数时，电导率和介电损耗会增加。为了兼顾高介电常数和低介电损耗，本研究通过溶液浇铸制备聚偏二氟乙烯（PVDF）/碳化铬（Cr2C3）/蒙脱石（MMT）三元复合薄膜。改善了基于界面极化的介电响应，提高了复合材料的介电常数。MMT陶瓷用于抑制界面漏电流。与PVDF/Cr2C3复合材料相比，三元复合材料的电导率和介电损耗有所降低。
