Abstract

Zinc oxide-silver (ZnO–Ag) particles and ZnO–Ag/poly(vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene)[P(VDF-TrFE-CTFE)] composites were synthesized by a reflux method and a solution route, respectively. The functions of ZnO and Ag particles on the dielectric properties of the composites were investigated. The effect of the molar ratio of ZnO to Ag on the composites was also studied. The results indicated that the optimum molar ratio of ZnO to Ag in the composites with 30 wt.% fillers was 0.6/0.4 for dielectric constant modifier applications. Furthermore, the optimum composite had a dielectric constant of 56 and a dielectric loss of 0.27 at 100 Hz and room temperature.

• Highlights for paper:

• The ZnO–Ag/P(VDF-TrFE-CTFE) exhibits excellent dielectric properties.

• ZnO is mainly used to distribute the Ag particles.

• Ag is mainly used to improve the dielectric constant of composites.

摘要

分别采用回流法和固溶法合成了氧化锌银（ZnO-Ag）颗粒和ZnO-Ag /聚偏二氟乙烯-三氟乙烯-氯三氟乙烯[P（VDF-TrFE-CTFE）]复合材料。研究了ZnO和Ag颗粒对复合材料介电性能的影响。还研究了ZnO与Ag的摩尔比对复合材料的影响。结果表明，对于介电常数改性剂应用，在具有30重量％填料的复合物中，ZnO与Ag的最佳摩尔比为0.6 / 0.4。此外，最佳复合材料在100 Hz和室温下的介电常数为56，介电损耗为0.27。
