Abstract
In this study, we report preparation and characterization of EVA/LLDPE/graphene oxide nanocomposite packaging films. Graphene oxide (GO) nanosheets were synthesized with modified Hummer’s method and used to improve various properties of EVA/LLDPE polymeric matrix. Nanocomposite films are prepared via solution casting methods. The SEM images and XRD patterns confirmed the formation of likely exfoliation structures and good interaction between matrix and nano-fillers. The mechanical properties of EVA/LLDPE were improved by adding low amount of GO so the tensile strength and Young modulus were increased 30% and 65%, respectively just by adding 5 wt.% GO. Furthermore, the oxygen permeability of matrix was dropped 500% by adding GO. Finally, it seems that EVA/LLDPE/GO nanocomposite films could be proper candidate for using in food packaging system
