摘要

We have made a composite film of graphene oxide with rich epoxide (GOre) from graphite material by oxidation method followed by the formation of thin layer by utilizing poly-vinyl alcohol (PVA). The structure of GOre was characterized by X-ray diffraction (XRD), the results supported by visualize a model from crystallography database. Maximum absorption spectra uv-vis GOre obtained in the 231 nm. Graphite, GOre and PVA were characterized by FT-IR to identified functional groups of each materials. FTIR results, confirm that the layer composite is formed by the hydrogen interaction of the oxide functional groups such as hydroxyl, ether, and epoxy. Furthermore, the electrical properties of the composites are identified by looking at conductivity and stability. Through different variations of the composition, the best conductivity and stability are obtained when PVA and GOre conditions in a combination of proportional weight.
