SILVER/POLY (LACTIC ACID)/PEG NANO-COMPOSITES WITH ANTIBACTERIAL PROPERTES

In this study antibacterial silver/PLA/PEG nano-composites were synthesized via chemical reduction method by dissolving various percentages of AgNO3 in aqueous phase that was dispersed in organic phase using sodium borohydride as a reducing agent. PEG was added to improve flexibility of high molecular weight poly (lactic acid) films. Presence of synthesized nano-particles of Agin polymeric matrix was demonstrated by UV-visible and XRD experiments. Both PLA as the polymeric matrix of the nano-composites and PEG are biodegradable and biocompatible polymers and Ag/PLAPEG nano-composite films could be used in food packaging applications to improve food quality.
