聚合物纳米电介质材料由于其出色的机械加工特性、电可调制特性已成为当今高密度封装技术等诸多学科的前沿领域。通过在聚合基体中引入高介电陶瓷或纳米导电颗粒形成具有高介电常数的复合材料，并通过印刷电路板(Printed Circuit Board，PCB)制备工艺内置于PCB基板内部形成埋入式元件(电容、电感及其他无源元件)，这已经在电子系统小型化方面显示出巨大的应用前景。文章综述了高介电纳米聚合物复合材料领域近年来的研究进展，探讨了聚合物纳米复合材料在埋入式电容器、电感器中的应用及埋入式无源滤波器的设计方法、制备工艺以及复合材料的电磁特性对埋入式元件电学性能的影响。%The inorganic particles iflled polymer composites have attracted considerable interests because of their good mechanical properties and tailorable performances by controlling the content of the ifller. The polymer composites with high permittivity by introducing high dielectric constant ceramics or conducting nanoparticles into the polymer matrix have shown tremendous application foreground. This review focuses on the progress of inorganic/polymer composites and applications in embedded passive devices in recently years. The design and fabrication of the embedded capacitor,inductor and iflter based on the Inorganic/Polymer composite were discussed. The effects of parameters including permittivity and permeability of composite on the performance of embedded passive devices were also investigated.
