“…The causes are a rise in the absorption coefficient as a result of electronic transit between bonding and nonbonding molecular orbits, as well as an increase in the extinction coefficient as a result of refractive index [18]. In ©SRP 2023, DOI: https://doi.org/10.47758/ijn.vi4.91 figures ( 5) and ( 6), the results observed that the real dielectric constant Ɛr and the imaginary dielectric constant Ɛi increase with increasing concentration of pomegranate dye [19].

This paper aims to fabricate a nanocomposite made of polyvinyl alcohol, titanium dioxide, and natural pomegranate dye that can function as a sunlight sensor for solar cells. The thin films' structural, optical and electrical properties of (Pomegranate/PVA-TiO2) were studied. Images from (FE-SEM) taken at a concentration of 0.3 weight percent revealed the structural features of the material., the surface of the (Pomegranate/PVA-TiO2) nanocomposite films demonstrations many aggregations or chucks arbitrarily dispersed of (TiO2) with grain size (47-55) nm. With an increase in natural dye content, transmittance decreases. Pomegranate dye had the most prominent peaks, measuring (76%) at a concentration of 1 ml. All optical constants, including parameters such n and k for transparency and extinction, r and i for real and imaginary dielectric constants, and electrical conductivity for optical conductivity, rise with pomegranate dye concentration. The results showed that the electrical conductivity at a concentration of (4 ml) recorded the greatest possible (6.4×10-6) (Ω.cm)-1, and the activation energy decreased with increasing concentration of pomegranate dye (0.29-0.20) eV. Then a solar cell was prepared from SnO2/Si, and the films were deposited on it, and the efficiency results were. After being coated with (Pomegranate/PVA-TiO2) nanocomposites, the efficiency (ƞ) increased from (4.3-4.75). In addition to the increase in current (Isc) from 23 to 30 mA/cm2. The final results showed that the (Pomegranate/PVA-TiO2) nanocomposite possesses a high transmittance, low activation energy and is sensitive to light in the Vis and IR regions, making it suitable for optical application.

This present work, includes the preparation of rubber batches containing silicone rubber (SIR) (80pphr) and polyurethane (PU) (20pphr) with micro-lead powder in different loading, respectively (0,20.40,60,80,100,150,200,250,300pphr). The mechanical properties measured the device universal tensometer, such as tensile strength, elongation and modulus of elasticity, according standard specified of (ASTM D-412) were followed and the hardness property measured by (Hardness Shore A) was put through its steps according to the standard specification (ASTMD-1415). The results were selected, and the sample (10) consisting of (SIR 80/PU20 and micro-lead 300pphr) was chosen because it is more suitable for the required mechanical properties. The results observed that the ratios of micro-lead loading increased, the tensile and elongation decreased, and the hardness and elastic modulus increased. Rubber batches reinforced with micro-lead were exposed to an infrared (FTIR) test device with the addition of hexane, where there were no changes in the infrared spectrum of the rubber composites (SIR80/PU20/Micro-Pb). Sample No. (10) was shown that the scanning electron microscope (SEM) before and after adding hexane, where it was noted that the image (A) without hexane, the absence of homogeneity of lead. As for image (B) in the presence of hexane, we note the homogeneity of lead and the distribution of lead equally, so that radiation examination were measured the Geiger counter of two sources of radioactive elements were used, the caesium source Cs137 and the cobalt source Co60. The radiation is attenuated through the material, while the thickness of the half (X1/2) gradually contrasts according to the attenuation of the radiation. This work is applied in the applications of shields as a protective suit against harmful radiation.

This research includes the manufacture of a polymeric nanocomposite consisting of silicone rubber/polyurethane as a base, with the addition of the first filler of micro-lead with a ratio of 300 pphr and the second filler of nano-lead with different ratios (0, 0.2, 0.4, 0.6, 0.8 pphr). With the addition of hexane (liquid state) to the superposition using the casting technique at room temperature. The structural properties of the surfaces of the samples were measured using Fourier transformation spectroscopy (FT-IR) and the scanning electron microscope (SEM). In addition to studying the mechanical properties represented by each hardness, tensile, elongation, and elastic modulus. (FT-IR) showed the absence of a chemical reaction for all samples. While SEM measurements showed a homogeneous distribution of micro-lead and nano-lead in the presence of hexane equally, and there were no voids in the eyes of the prepared rubber equally. For the mechanical properties, we see that the hardness, tensile strength and modulus of elasticity continue to improve with the increase in the number of lead nanoparticles. And a decrease in elongation as a result of inverse proportion to the modulus of elasticity. From the results obtained, this composite can be used in gamma ray attenuation applications in shielding, especially in medical and industrial fields.
