摘要
In this study, starch-PVA based composite films combined with nano SiO2 were prepared by a solvent casting technique. Different amounts of nano SiO2 additives were added to starch-PVA films and the results were evaluated. Accordingly, in starch-PVA films containing nano SiO2 added in the ratio of 1%, 3%, and 5% by mass, nano SiO2 was homogeneously distributed on the surface of the composite films. However, loss of elasticity was observed in films from containing 3% nano SiO2 onwards. The unique properties of nanocomposite films obtained with small amounts of nanomaterial reinforcement have been demonstrated. Composite films have been characterized by Fourier-transform infrared spectroscopy, UV–Vis spectrophotometry, and field emission scanning electron microscopy. Fogging tests were compared. Less nano SiO2 additive in the samples showed the best anti-fogging behavior. This study aims to demonstrate the potential use of starch-PVA nanocomposite films with unique properties in food packaging applications. The surface of starch/PVA films is strengthened by the deposition of SiO2 nanoparticles.
