摘要: We studied the green synthesis and antibacterial activity of chitosan-silver (Ag) nanocomposite films for application in food packaging. Green Ag nanoparticles (AgNPs) was achieved by a chemical reaction involving mixture nitrate (AgNO₃) an autoclave at 0.1 MPa, 121℃, 15-120 s. The formation AgNPs chitosan confirmed both UV-Visible spectrophotometry transmission electron microscopy (TEM) effects chitosan-AgNO₃ concentration time on were examined. resulting chitosan-Ag composite characterized various analytical techniques their evaluated based halo zones around films, indicating inhibition growth Escherichia coli. A fourier-transform infrared (FTIR) spectroscopy analysis showed that free amino groups acted as effective reductants AgNP stabilizers. exhibited enhanced with increasing content surface as-prepared films.
