复合材料已被广泛研究用于介电和相关应用。本文综述了高介电常数聚合物基0-3型复合材料的研究进展。这些复合材料分为两类：电介质-电介质复合材料和导体-电介质复合材料。给出了物理原理和相关模型以及相关的假设和近似。通常，介电-介电复合材料需要比导体-介电复合材料更高浓度的填料以达到高介电常数。在导体-介电复合材料中观察到的高介电常数通常与高介电损耗和低电击穿场相关联。实验结果进行了总结，以说明这些复合材料的发展的原则，和成就。讨论了这些复合材料在不同应用中的基本认识和进一步发展所面临的挑战。
Composites have been extensively studied for dielectric and related applications. This is a review of polymer based 0–3 composites that exhibit a high dielectric constant. These composites are classified into two types: Dielectric–dielectric composite and conductor–dielectric composite. The physical principles and related models are presented with associated assumptions and approximations. In general, a dielectric–dielectric composite needs a higher concentration of the fillers to reach a high dielectric constant than a conductor–dielectric composite. The high dielectric constant observed in the conductor–dielectric composites is usually associated with a high dielectric loss and a low electric breakdown field. The experimental results are summarized to illustrate the principles for, and the achievements in, the development of these composites. The challenges facing the fundamental understanding and the further development of these composites for different applications are discussed.
