In this paper, silver (Ag) nanoparticles were synthesized by utilizing an aqueous extract of fresh leaves Chenopodium murale which is considered a cost-effective and eco-friendly approach. The sol-gel technique was used to syntheses TiO2 different methods characterize the (Ag TiO2) including UV–Vis spectroscopy, XRD, TEM. Also, new nanocomposites prepared using solution casting method. films characterized analytical methods. absorption peak shown UV–visible spectrum around 430 nm. crystalline average size Ag NPs 20 nm while 15 as displayed XRD pattern. Meanwhile, degree amorphicity Cs/PEO blend increased result adding NPs. It evident through FTIR spectroscopy that there interaction between functional groups polymer Ag/TiO2 nanofiller. addition, increase mechanical properties such Young's modulus, elongation, tensile strength with increasing content. clear impedance spectroscopic study iconic conductivity improved addition into system. highest log −9.34 S cm−1 at Cs/PEO/0.3%Ag/0.8%TiO2. also from results antibacterial activity pure doping blend. index (%) sample + (0.3%) (0.8%) E. coli, S. aureus, C. Albicans, A. niger 32, 45.8, 77.8, 92 respectively. Thus, these indicate applicability potential for use in food packaging applications.
