Preparation and Evaluation of Nanocomposite LDPE Films Containing Ag and ZnO for Food-Packaging Applications

摘要

Nanocomposite polymer films were produced from composites comprising LDPE /nanosilver and LDPE/nano-ZnO by melt compounding. The mechanical properties of the films prepared were characterized by using stress-strain analysis. Dispersion quality of nanomaterials into the polymer matrix film was monitored using the Transmission Electron Microscopy. The results showed the nanocomposites as possessing lower elongation at break and more antimicrobial activity with the increase of each of nanofillers content.
