초록

A novel antibacterial paper coated with chitosan-based silver (Ag) nanocomposite prepared by greensynthesis has been investigated for a wide range of application in food, agricultural and medicalpackaging. Green synthesis of Ag nanoparticles (AgNPs) was carried out by a chemical reaction involvinga mixture of chitosan-silver nitrate (AgNO3) in an autoclave at 15 psi, 121℃, for 15-120 sec. AgNPsand their formation in chitosan were confirmed by both UV-Vis spectroscopy and transmission electronmicroscope (TEM). Fourier transform infrared spectroscopy (FTIR) study showed that free aminogroups in chitosan act as an effective reductant and AgNPs stabilizer. Antibacterial test of coated paperwith as-prepared chitosan-AgNPs was performed qualitatively against E. coli based on the formation ofhalo zones around coated papers and it was shown to be effective in suppressing the growth of E. coliwith increasing Ag contents in coating layer.
