Natural polymers derived from agricultural products are the major resource for developing renewable and biodegradable polymer materials. In this work, we present a simple and green approach to fabrication of wheat gluten (WG) /chitosan (CS) /graphene (Gr) nanocomposite films. WG/CS/Gr nanocomposite films were prepared in a casting and solvent evaporation method. Three different mixing sequences were attempted in the present work: (1) to mix WG and CS first, and then mix it with Gr; (2) first to mix WG and Gr, and then mix it with CS; (3) to prepare CS/Gr hybrid first, and then mix it with WG. The structure and properties of these nanocomposites were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and thermal gravimetric analysis (TGA). It was found that the blending sequence significantly influences the microstructure of WG/CS/Gr ternary hybrids and the dispersion behavior of the graphene in the polymer matrix. |
