The Improvement in Mechanical and Barrier Properties of Poly(Vinyln Alcohol)/Graphene Oxide Packaging Films

摘要

In this study, poly(vinyl alcohol) (PVA)-graphite oxide and PVA-graphene oxide (XGO) films were prepared by simple and environmentally friendly method. Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscope revealed the strong hydrogen-bonding interactions between XGO and PVA matrix and the layered structure of tensile fracture surfaces of exfoliated PVA-XGO films. These resulted in a remarkable improvement on mechanical and barrier properties of XGO/PVA nano
