“…The effect is in accordance with numerous theoretical models valid for spatially fixed particles, embedded in a matrix with lower permittivity [19–21]. This behavior is very similar to that observed for other composites made from ceramics and polymers such as SBN70‐PVC [22], PZT‐PVDF [23], PLZT‐P(VDF/TFE) [24] and BNTN‐PVC [25], for example, PPS shows a weak dependence of ε′ on the frequency, contrary to PET and the composites. This fact results from the presence of polar groups in PET and composites consequently.…”

Polymer/ceramic nanocomposites designed for application as electronic packaging were prepared using corotating twin‐screw extruder. The dielectric properties of the composites made from polyethylene terephthalate (PET), polyphenylene sulfide, and barium titanate were studied as a function of BaTiO3 fraction in the range between 0.75 and 1.5 wt%. Processing parameters were optimized in order to obtain the nanocomposites with appropriate dielectric properties like dielectric permittivity ε′, dielectric losses ε″, and their temperature stability in a wide frequency range. The measurements showed the increase of the dielectric permittivity value ε′ in the composites in comparison to both pure polymers. The dielectric loss factor tgδ of the composites was found to be much smaller than that of the pure PET. The weak influence of the ceramics on the temperature stability of the dielectric properties of the composites was stated. POLYM. ENG. SCI., 50:1613–1619, 2010. © 2010 Society of Plastics Engineers
