Abstract

A new composite (PPy/Fe₂O₃)/PET was created by mixing polypyrrole (PPy) with iron oxide (Fe₂O₃) and then depositing the resulting blend (PPy/Fe₂O₃) onto a polyethylene terephthalate (PET). After utilizing oxidative chemical polymerization to construct the composite, the samples were examined using X-ray diffraction (XRD), X-ray photoelectron (XPS), and infrared (FTIR) techniques. The XRD confirms that the (PPy/Fe₂O₃)/PET composites were successfully fabricated. The conductivity of PET is 4 × 10⁻⁸ S·cm⁻¹, increased for the composites (PPy/Fe₂O₃)/PET to 6.1 × 10⁻⁵ S·cm⁻¹. Additionally, the effects of argon beam bombardment with cold cathode sources (4 × 10¹⁶, 6 × 10¹⁶, and 8 × 10¹⁶ ions.cm⁻²) on (PPy/Fe₂O₃)/PET composites were investigated. Furthermore, the surface energy and the contact angle were determined. As a result of this study, irradiated nanocomposite films have new physico-chemical characteristics that may find uses in the storage energy devices. The results showed that the irradiated composite are greatly improved, allowing these films to be used for a range of applications, including coating and printing devices.

介质用辐照柔性PPy/Fe2O3/PET聚合物纳米复合薄膜的制备、结构表征和表面研究

将聚吡咯（PPy）与氧化铁（Fe2O3）混合，然后将所得混合物（PPy/Fe2O3）沉积在聚对苯二甲酸乙二醇酯（PET）上，制备了一种新的复合材料(PPy/Fe2O3)/PET。利用氧化化学聚合法制备复合材料后，利用x射线衍射（XRD）、x射线光电子（XPS）和红外（FTIR）技术对样品进行了检测。XRD证实了(PPy/Fe2O3)/PET复合材料的成功制备。PET的电导率为4 × 10−8 S·cm−1，复合材料(PPy/Fe2O3)/PET的电导率为6.1 × 10−5 S·cm−1。此外，研究了冷阴极源氩束轰击（4 × 1016、6 × 1016和8 × 1016离子。cm−2）对(PPy/Fe2O3)/PET复合材料的影响。测定了表面能和接触角。研究结果表明，辐照纳米复合薄膜具有新的物理化学特性，可用于储能器件。结果表明，辐照复合材料得到了极大的改善，使这些薄膜可用于一系列应用，包括涂层和印刷设备。图形抽象
