Dependence of Dielectric Properties on Zn-Based Ceramic Fillers of the Polystyrene-Matrix Composites

摘要

Effects of ZnTa₂O₆, ZnWO₄ and ZnMoO₄ (Zn-based) ceramic content on the dielectric properties of Polystyrene (PS)/Zn-based ceramic composites were investigated as a function of frequency. With increasing of Zn-based ceramic content, the dielectric constant (K) and dielectric loss (tan δ) of the composites were increased. These results are due to the connectivity among the ceramic particles and interfacial polarization between PS and ceramics. Several types of theoretical models have been employed to predict the effective dielectric constant of the composites. The temperature coefficient of resonant frequency (TCF) was also discussed for thermal stability of the composites.View full textDownload full textKeywordsDielectric properties, composites, polystyrene, Zn-based ceramicsRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10584587.2010.488551
