Abstract

Herein, (PPy-Ag)/PET composites, consisting of silver nanoparticles (AgNPs) and polypyrrole (PPy) coated on PET, were fabricated by the polymerization process and then the films were characterized by SEM and XRD techniques. The addition of PPy-Ag on the dielectric properties of PET were determined. The XRD proved the successful synthesis of the (PPy-Ag)/PET samples. The SEM results demonstrate the effect of Ag modified the characteristics of the composite, which confirmed the interaction of (PPy-Ag)/PET. The dielectric properties of the films in frequency of 50 Hz to 5.6 MHz were measured. The density energy was enhanced from 9.1 × 10−5 for PET to 5480 × 10−5 J m−3 for (PPy-Ag)/PET. Moreover, the relaxation time decreased from 1.7 × 10−5 for PET to 2.8 × 109 sec for (PPy-Ag)/PET. The obtained data confirm the incorporation of PPy-Ag by PET. This research has led to the development of novel physico-chemical properties in flexible polymeric nanocomposite films, which could be used in high-performance energy storage devices.

在 PET 薄膜上沉积银纳米粒子与聚吡咯的结构特征和介电性能，用于介电器件

本文通过聚合工艺制备了银纳米粒子（AgNPs）和聚吡咯（PPy）涂覆在 PET 上的（PPy-Ag）/PET 复合材料，然后利用 SEM 和 XRD 技术对薄膜进行了表征。测定了 PPy-Ag 的添加对 PET 介电性能的影响。XRD 证明了 (PPy-Ag)/PET 样品的成功合成。扫描电镜结果表明，Ag 改变了复合材料的特性，证实了 (PPy-Ag)/PET 的相互作用。测量了薄膜在 50 Hz 至 5.6 MHz 频率范围内的介电性能。密度能从 PET 的 9.1 × 10-5 提高到 (PPy-Ag)/PET 的 5480 × 10-5 J m-3。此外，弛豫时间从 PET 的 1.7 × 10-5 下降到 (PPy-Ag)/PET 的 2.8 × 109 秒。所获得的数据证实了 PET 与 PPy-Ag 的结合。这项研究开发出了具有新型物理化学特性的柔性聚合物纳米复合薄膜，可用于高性能储能设备。
