使用光学显微镜观察采用溶剂蒸发法合成的包裹GO的微胶囊的分散状态。样品制备：微胶囊分散于水中，取一滴样品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。微胶囊制备：在转速2000rpm下，以NSF3007C作为乳化剂，乳化剂浓度2wt%，温度40℃，持续4h。

Use an optical microscope to observe the dispersion state of GO-coated microcapsules synthesized by solvent evaporation. Sample preparation: Microcapsules are dispersed in water, take a drop of sample and drop it on a glass slide, put on a coverslip, and adjust the multiple until the microcapsules are clearly observed. Microcapsule preparation: At a rotational speed of 2000rpm, NSF3007C was used as an emulsifier, the emulsifier concentration was 2wt%, and the temperature was 40 ° C for 4h.
