摘要

开发具有高介电常数的材料对电子器件的小型化具有重要意义。从这个角度来看，采用热等静压法制备了重量高达15%的Sr2TiMnO6 (STMO)陶瓷聚四氟乙烯(PTFE)复合材料，并对其介电和热行为进行了表征。x射线衍射图显示，复合材料中出现了与PTFE和STMO相对应的峰，但峰的强度与STMO的载荷有关。复合材料的热稳定性优于纯聚四氟乙烯。STMO的加入提高了聚四氟乙烯的介电性能。这些具有高介电常数的复合材料可以进一步探索其在电容器中的应用。

Dielectric and Thermal Behavior of PTFE/Sr2TiMnO6 (STMO) Composites

Development of materials with high dielectric permittivity is very much important for the miniaturization of electronic devices. From that perspective, polytetrafluoroethylene (PTFE) composites with up to 15 weight% Sr2TiMnO6 (STMO) ceramics were prepared using hot isostatic pressing method and characterized for their dielectric and thermal behavior. X-ray diffraction patterns showed the appearance of peaks corresponding to both PTFE and STMO in their composites, however, the intensities of the peaks were dependent on the loading of STMO. Thermal stability of the composites was superior to that of pure PTFE. Enhancement in the dielectric properties of PTFE was obtained from the addition of STMO. These composites with high permittivity can be explored further for their possible use in capacitor applications.
