Graphene-chitosan nanocomposite film by reduction of graphene oxide within chitosan networks |
| 초록 |
Graphene oxide (GO) was prepared by Hummer’s method. The graphene-chotosan nanocomposite film was obtained via reduction of GO that was carried out in the chitosan networks using hydrazine. There were two steps. First, the GO was dispersed in 2 wt% of chitosan solution where chitosan solution was prepared by 2 wt% of aqueous acetic acid and then casted the GO-chitosan mixture into a film. The other, the GO-chitosan composite film was reduced by hydrazine monohydrate at 95oC. We confirmed the reduced GO (rGO) and alteration of amorphous region in the nanocomposite film using X-ray diffraction (XRD). Raman spectroscopy was also employed to confirm the oxidation and reduction state of the graphene. The morphology and internal structure were characterized by scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) respectively. In this study, the effect of reduction of GO within the chitosan networks was confirmed that will do act on improving mechanical properties of flexible composite film valuably. |
