Preparation, characterization and antibacterial activity of chitosan-g-poly acrylonitrile/silver nanocomposite.
Chitosan-grafted-poly acrylonitrile silver nanocomposites (Cs-g-PAN/Ag) were prepared via in-situ chemical reduction of Ag ions in graft copolymerization of acrylonitrile onto chitosan. Graft copolymerization process was provided by FTIR and gravimetric methods. UV spectra and TEM images show silver nanoparticles with average 15-20nm dispersed homogeneously in CS-g-PAN/Ag nanocomposite-ray and TGA evident the change in crystallography and thermal stability in consequence of presence Ag nanoparticles. Cs-g-PAN/Ag nanocomposite showed excellent antimicrobial performance towards bacteria such as Escherichia coli and Staphylococcus aureus.
