BSCT/PVDF复合材料的热学和宽频介电性能
BSCT/PVDF composites were prepared by solution casting with DMF as solvent. The addition of BSCT had significant influence on the crystallization, melting, and glass transition behaviors of the PVDF matrix. The dielectric properties of the BSCT/PVDF composites were also studied over a wide frequency range from 100Hz to 1GHz and a wide temperature range from -50℃ to 100℃ to establish the frequency and temperature dependence. Highεup to 132 at 100 Hz and low tan 8 down to 0.0045 at 1 GHz were achieved for some BSCT/PVDF composites. Therefore, considering the general requirements of embedded capacitors for integrated electronic devices (highεand low tanδ), the BSCT/PVDF composites could be an appropriate candidate. The obtained data of s were also theoretically predicted by different models and the modified. Lichtenecker equation and Jayasundere-Smith equation yielded the best match.
