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

A. Ashokbabu, P. Thomas

Open publisher page 2 citations

Abstract

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.
