Preparation of Reduced Graphene Oxide/Chitosan Composite Films with Reinforced Mechanical Strength

Reduced graphene oxide (rGO)/chitosan composite films were fabricated by a solvent casting method and cross-linked using genipin. Their properties were characterized by scanning electron microscopy, X-ray powder diffraction, Raman spectroscopy, and UV-Vis spectroscopy. When rGO was added the tensile strength and membrane rigidity of the films increased, but their swelling ability in water decreased.
