使用光学显微镜观察用Hummers法、8000目石墨粉制成的改性的氧化石墨烯水溶液的分散状态。样品制备:取一滴改性的氧化石墨烯水溶液滴于载玻片后放上盖玻片,调整倍数直至清晰观察到微胶囊。
The dispersion state of modified graphene oxide aqueous solution made by Hummers method and 8000 mesh graphite powder was observed by optical microscope. Sample preparation: Take a drop of modified graphene oxide aqueous solution and put it on a coverslip, and adjust the multiple until microcapsules are clearly observed.
