使用光学显微镜观察用Hummers法、8000目石墨粉制成的氧化石墨烯水溶液的分散状态。样品制备:取一滴未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 the aqueous solution of graphene oxide made of 8,000-mesh graphite powder by Hummers method was observed using an optical microscope. Sample preparation: Take a drop of unmodified graphene oxide aqueous solution and drop it on a glass slide, put it on a coverslip, and adjust the multiple until the microcapsules are clearly observed.
