与一般的“超材料”不同，“超复合材料”是指具有负介电常数的随机纳米复合材料，这种负介电常数是通过控制其微观结构和组成来决定的。具有独特负介电常数的超复合材料在超导体、滤波器、电容器、电磁干扰屏蔽或吸收等领域具有潜在的应用前景。本文讨论了用于分析负介电常数的德鲁德模型、洛伦兹模型和“双纳米线”模型。综述和分析了以碳纳米材料为填料的超复合材料的制备方法、性能和负介电常数的产生机理。此外，还讨论了超复合材料在电磁波吸收和提高天线性能方面的应用。
Different from common “Metamaterials”, “Metacomposites” are used to describe random nanocomposites with negative permittivity, which is determined by controlling their microstructures and compositions. Metacomposites with unique negative permittivity show potential applications in superconductors, wave filters, capacitors, electromagnetic interference shielding or absorbing and other fields. In this review, Drude model, Lorentz model and “double nano wires” model used to analyze negative permittivity were discussed. Preparation, properties and mechanism of negative permittivity from metacomposites in corporation of carbon nanomaterials as fillers were reviewed and analyzed. Besides, the applications of metacomposites in the field of electromagnetic wave absorption and improving the performance of the antenna were also discussed.
