“…This low fluence is useful for technically induced changes in composite materials, as indicated before. [17][18][19][20][21] Additionally, the films' structural integrity can be compromised at fluence levels exceeding certain thresholds. The Ar+ beam was extracted using the hand-made ion source as previously reported, 22 as seen in Fig.…”

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

“…A wide variety of applications make use of polymeric nanocomposites, some of which include optical waveguides, antistatic materials, biosensors, batteries, and super capacitors [5]. In addition, polymer nanocomposites can have their optical properties ne-tuned by adding nanoparticles, leading to enhanced transparency [6][7][8]. Many industries, including those dealing with paper and packaging, rely on adhesives that have PVA bases [9].…”

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.

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.
