“…These bands suggest that the cellulose has undergone acetylation. 28 In addition, the carboxylate group of C-O-C rings is indicated by a strong peak at 1230 cm −1 , while the pyranose ring is observed at 1035 cm −1 . Irradiated CA/PANI exhibits a decreasing FTIR peak intensity with increasing ion irradiation.…”

This work study the effects of argon beam irradiation on surface properties of CA/PANI films using cold cathode source with varying ion fluences (4×1014, 8×1014, and 12×1014 ions/cm2). The EDX, SEM and FTIR methods verified successful fabrication of the composites. Surface free energy, contact angle, and work of adhesion were measured for both the pure and irradiated films. Raising the ion flux from 4x1014 ions.cm-2 to 12x1014 ions.cm-2 it decreases the contact angle of CA/PANI from 62.1o to 43.4o and increases the surface free energy from 46.7 to 63.9 mJ/m2. The results showed that the CA/PANI changed after exposed to radiation, proving that the irradiated surface properties were improved. In addition, their electrical conductivity was tested in the frequency range of 50 to106 Hz for CA/PANI films. When subjected to 12x1014 ions.cm-2, the conductivity rose from 1.1×10-8 S/cm for CA/PANI to 6.5×10-7 S/cm. The results showed that the irradiated CA/PANI had better electrical and surface properties, which is crucial for many devices including batteries and supercapacitors

“…The band 830 cm −1 referred to CH 2 stretches. Due to the interaction between TiO 2 and PVA/Cs levels, these peaks were seen in all spectra with a slight shift [ 32 ]. Moreover, due to charge transport complexes, PVA/Cs/TiO 2 composite films had a different intensity than pure PVA/Cs [ 33 ].…”

This research paper aims to fabricate flexible PVA/Cs/TiO2 nanocomposite films consisting of polyvinyl alcohol (PVA), chitosan (Cs), and titanium oxide (TiO2) for application in energy storage devices. The samples were analyzed using X-ray diffraction (XRD), atomic force microscope (AFM), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and energy dispersive X-ray (EDX) techniques. The impact of TiO2 on the electrical impedance, conductivity, permittivity, and energy efficiency of the PVA/Cs was determined in a frequency range of 100 Hz to 5 GHz. The XRD, FTIR, and EDX results showed the successful fabrications of the PVA/Cs/TiO2. The SEM and AFM images illustrated that the TiO2 was loaded and distributed homogenously in PVA/Cs chains. In addition, the electrical conductivity was enhanced from 0.04 × 10−7 S.cm−1 of PVA/Cs to 0.25 × 10−7 S.cm−1 and 5.75 × 10−7 S.cm−1, respectively, for the composite PVA/Cs/0.01TiO2 and PVA/Cs/0.1TiO2, and the dielectric constant grew from 2.46 for PVA/Cs to 7.38 and 11.93, respectively. These results revealed that modifications were made to the produced films, paving the way for using the composite PVA/Cs/TiO2 films in different energy applications, such as electronic circuits and supercapacitors.

“…15,16 One of the main advantages of an ion beam irradiation is increase the interfacial contact of nanofillers and the polymer matrix. 17,18 Additionally, ion irradiation has been shown to be more successful than electrons in the field of particles beam approaches at altering a polymer surface. This is a result of the increased ionization crosssection of the energetic ions as compared to electron.…”

In this research, the casting solution manufacturing approach was used to mix polyvinyl alcohol (PVA) and copper oxide (CuO) to create the composite (PVA/CuO). X-ray diffraction analysis and Fourier transform infrared spectroscopy were applied to record the successful fabrications of the composites. Next, argon ion beams at fluencies of 2.5x1017, 5x1017, and 7.5x1017 ions.cm-2 were used to irradiate the composites. In frequencies of 50 Hz to 6 MHz, the dielectric characteristics of PVA/CuO were modified by the ion irradiation. The dielectric constant was enhanced from 39 for unmodified PVA/CuO to 356 for the irradiated composite by 7.5x1017 ions.cm-2, and the conductivity changed from 0.05x10-6 S/cm to 2.9x10-6 S/cm. However, the potential barrier decreased from 0.24 eV for PVA/CuO to 0.21, 0.16, and 0.15 eV, respectively, for 2.5x1017, 5x1017, and 7.5x1017 ions.cm-2, and the relaxation time decreased from 9.36x10-8 sec for PVA/CuO, to 6.58x10-8 sec for 7.5x1017 ions.cm-2. The results indicate that the irradiated PVA/CuO nanocomposite can be used in a number of devices such as capacitors and batteries.
