Preparation, structural characterizations and surface studies of irradiated flexible PPy/Fe2O3/PET polymer nanocomposite films for dielectric applications‏

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.
