In the current research, silver nanoparticles (AgNPs) were mixed with a polymer blend to enhance their optical and electrical properties and antibacterial efficiency. A novel approach via introducing AgNPs into the polymer blend could improve the physical and antibacterial characteristics of the nanocomposites (NCs). In the loading process, two different amounts of AgNPs were respectively encapsulated with polyvinyl alcohol (PVA), polyacrylamide (PAAm) and polyethylene oxide (PEO) polymeric blend via casting method. The prepared films were characterized by X-ray, optical microscope (OM), scanning electron microscopy (SEM), Fourier transformation infrared (FTIR) and UV/Visible. The OM and SEM images showed that the AgNPs were well diffused inside the polymer blend with some weak aggregations. The optical properties were enhanced after doping. The NCs films absorbed UV-ray at (λ=220 nm). The indirect energy gap decreased after loading from 3.80 to 3.10 eV but the direct energy gap decreased from 4.25 to 3.75 eV. The AC electrical properties were studied in the frequency range between 100 Hz to 5 MHz. The dielectric constant and loss of NC films were decreased with the increase of AgNPs, while the electrical conductivity increased. The inhibition zone diameters of Escherichia coli bacteria increased with the increasing of AgNPs contents.

“…This behavior emphasizes non-Debye activity for polymer electrolytes. Due to a lack of time, they cannot obey the field separation at high f values [45][46][47]. Both coefficients decrease with the increase of CSNP contents, and this result may be attributed to an increase in the AC conductivity due to an increase in CSNPs density [48].…”

The present study was conducted to explore the impact of corn starch nanoparticles (CSNPs) on the morphological, optical, and dielectric behaviors of the PVA/PMMA/PAAm (PPP) hybrid polymer matrix. The resultant PPP-CS nanocomposite films were synthesized employing the solvent casting procedure. Scanning electron microscope(SEM) images of the as-synthesized films revealed the successful embedding, homogeneity, and fine dispersion of CSNPs within the host PPP. No changes in the infrared ray(IR) band positions were seen upon embedding. The absorbance-λ chart illustrated an absorption band at 220 nm with red-shift toward higher wavelengths, which points out the semi crystalline structure of PPP-CS films. The optical coefficients were improved upon inclusion of CSNPs. The optical bandgap energy reduces from 4.50 to 4.12 eV as CSNPs' weight percentage increases from 0 wt% to 4 wt%. Furthermore, the refractive index values for PPP-CS films are in the range of 0.5 and 2.5. The dielectric constants of the obtained films decreased with the increase in CSNPs, except for the conductivity. The embedding of a small amount of CSNPs into the hydrophilic matrix significantly improved the composite's bioactivity. The inhibition zone diameters of Staphylococcus aureus bacteria were calculated to be 0, 26, and 32 mm for 0 wt%, 2 wt%, and 4 wt% CSNPs, respectively. The findings of this study are significant for the development of novel nanocomposite materials with antibacterial activity for optoelectronic device applications.

Initial production of the titanium dioxide nanoparticles TiO2 used the hydrothermal process. The onion peels and chitosan peel extracts, which are made using the Bio-synthesize approach. By using (UV-Vis) properties, the structural characteristics of TiO2 and TiO2 with extract from onion peels and chitosan peels were studied, and find the absorption edge of TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels is around 236 nm, 244 nm and 237.5 nm respectively. The pattern of TiO2 for a number of peaks suggested a tetragonal rutile phase, according to X-ray diffraction (XRD) research. Energy dispersive X-ray, (EDX) was done for TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels. Field emission scanning electron microscopy (FE-SEM) shows that the diameters ranging of TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels from (43.32 nm to 47.77 nm), (34.11 nm to 62.77 nm) and (32.22 nm to 35.11 nm) respectively. Studying was done on the effect of TiO2 & TiO2 with extracts nanoparticles on bacterial growth, a variation was observed in the effect of the TiO2 & TiO2 with extracts on the growth of bacteria.
