摘要: Graphene oxide (GO) was combined with wheat gluten (WG) and chitosan (CS) to prepare bionanocomposite films using a casting method. The were characterized variety of techniques, including scanning transmission electron microscopies, atomic force microscopy, X-ray diffraction, thermogravimetric analysis, Fourier transform infrared spectroscopy, mechanical testing, water swelling, oxygen permeability contact angle measurements, determine the effects GO on formation, structure properties bionanocomposites. Their formation found be dependent mixing order three components. added strengthen films, as well decrease absorption permeability. These attributed good dispersion in WG/CS matrix enabled by hydrogen bonds. decreased could explained increased hydrophobicity. notable improvement result addition makes suitable packaging materials. © 2016 Society Chemical Industry
