“…The previously chemical polymerization method is applied to create the PPy-Fe 2 O 3 material and PET/(PPy-Fe 2 O 3 ) film composites. 23,24 The pyrrole solution is mixed with 1.75 ml of Fe 2 O 3 , and the combination was stirred for 5 h to prepare the specimens. Furthermore, 1.25 g of ammonium persulfate (NH 4 )2S 2 O 8 was dispersed in extremely pure water and injected dropwise while vigorously swirling to the pyrrole, Fe 2 O 3 , and HCl mixture.…”

The films were characterized by different methods as FTIR, SEM, XRD and TGA to prove the efficient manufacturing of the composite. The dielectric performance measurements were done at frequency of 20 Hz to 6 MHz for the polymer PET and the composite (PPy-Fe2O3)/PET with varying concentrations of Fe2O3. Moreover, to reveal the characteristics of the fabricated composite, the contact angle, the work of adhesion, surface energy of the composite PET/(PPy-Fe2O3) films were considerably determined. The SEM results support the deposition of PPy-Fe2O3 composite on the PET surface. The water contact angle drops from 78.32 o for PET to 40.11o for PET/6%(PPy-Fe2O3), while the dispersive free energy raised from 23.9 mJ/m2 to 43.7 mJ/m2and the polar free energy rises from 8.9 mJ/m2 to 22.3 mJ/m2. The concentration of Fe2O3 increased the surface features of the samples, according to the obtained results. At frequency of 100 Hz, the dielectric constant enhanced from 18 for PET to 923 for the PET/6%(PPy-Fe2O3), and the dielectric loss improved from 24 to 9231, while the energy density improved fromm 7.9x10-5 J/m3 for PET to 408x10-5 J/m3. The TGA results show marginal modifications in thermal stability after deposition the PPy/Fe2O3 on the PET film.

The solution casting production process was used to synthesis the composite PVA/CuO that is consisting of copper oxide nanoparticle (CuONP) with polyvinyl alcohol (PVA) for use in optoelectronic. The PVA/CuO composite were then irradiated with argon fluences of 3x1017, 6x1017, and 9x1017 ions.cm− 2 by cold cathode ion source. The XRD, FTIR, and UV/Vis are employed to investigate the structural, functional group, and optical impacts of PVA/CuO. In addition, the dispersion properties of the investigated films were calculated using the Wemple and Di-Domenico method, which led to the determination of various optical parameters. Pure and irradiated films were estimated for their optical susceptibility and refractive index. At the fluence of 6x1017 ions.cm− 2, the single oscillator energy Eo rises from 3.25 eV for the un-irradiated film to 3.89 eV and the dispersion energy Ed rises from 0.098 eV to 0.26 eV. Therefore, the results reveal that irradiated PVA/CuO composite are more applicable for optoelectronics.
