Silver nanoparticles (Ag NPs) were synthesized using Capsicum annuum extract, which is a cost-effective and green technique. At the same time, selenium (Se prepared by sol-gel Then, series of PVA/SA blend samples filled with different contents Ag–Se via solution casting way. The nanocomposite films investigated measurements. XRD scans nanocomposites displayed decrease in crystallinity increasing content NPs as nanofillers matrix. FT-IR spectra indicated complexation positive interactions between NPs. thermal stability polymeric was improved after addition nanofiller (Ag–Se NPs), shown TGA scans. Moreover, indirect/direct optical energy gap decreased from 3.96/5.28 to 2.73/3.59 eV concentrations NPs, confirming improvement properties samples, UV/visible spectra. Dielectric studies revealed that filling increases defects leads greater number dipoles within and, thus, an increase dielectric constant loss samples. antibacterial test showed all had broad activity against Gram-positive Gram-negative bacteria compared pure it linearly related Improvements thermal, optical, electrical make present suitable for multiple functions many applications, such high-density storage flexible electronic devices. In contrast, enhancement could indicate these can also be used packaging biomedical purposes.
