摘要
采用溶液铸造法制备了聚偏氟乙烯-共六氟丙烯(VDF-HFP)基体中聚乙烯吡啶烷酮(PVP)-改性铋铁氧体(BFO)颗粒的介电性能。当pvp改性BFO颗粒的质量分数为40%时,复合材料的介电常数提高(90),介电损耗降低(<0.5)。与未改性BFO- p (VDF-HFP)复合材料相比,pvp改性BFO- p复合材料的介电常数要高得多。pvp改性BFO-P(VDF-HFP)复合材料的最大残余极化达到(2Pr ~ 1.12µC cm−2)。该方法可能为使用pvp改性BFO颗粒来提高复合材料的介电和铁电性能提供了一条途径。
Poly(Vinylpyrrolidone)-Embedded Bismuth Ferrite—Poly(Vinylidene Fluoride-co-Hexafluoropropylene) Composites with Enhanced Dielectric Properties
The dielectric properties of poly(vinylpyrrolidone) (PVP)-modified bismuth ferrite (BFO) particles in the poly(vinylidene fluoride-co-hexafluoropropylene) (P(VDF-HFP) matrix were prepared through solution casting techniques. The composites showed enhanced dielectric constant (90) and reduced dielectric loss (<0.5) at 40 wt% of PVP-modified BFO particles. The dielectric constant of the resultant composites with PVP-modified BFO was much higher as compared to that of unmodified BFO-P(VDF-HFP) composites. The maximum remnant polarization reached (2Pr ∼ 1.12 µC cm−2) in the PVP-modified BFO-P(VDF-HFP) composites. The demonstrated approach might provide a route for using PVP-modified BFO particles to enhance the dielectric and ferroelectric performance of the composites.
