Solubility and Diffusivity of Oxygen in Thin Film made of Polymer/Graphene Oxide Composite |
| 초록 |
In this work, we studied on improving gas barrier and transmittance of nanocomposites. Poly(vinyl alcohol)/graphene oxide(GO)/single-wall carbon nanotube(SWCNT) nanocomposites were prepared with various GO/SWCNT concentrations with solvent mixing method and characterized by X-ray diffraction(XRD). Light transmittance of nanocomposites was measured with UV-vis at 550nm. Gas barrier of nanocomposites was measured with Illinois Instrument Model 8001. The differential scanning calorimetry(DSC) pettarn of samples were measured with DSC at a heating rate of 10℃/min. XRD experiments were performed directly on the hybrid samples with Cu irradiation at the scanning rate of 0.02/s in the 2 range of 240. Morphology of nanocomposites was characterized with Scanning electron microscopy. |
