| 摘 要： | 采用改进Hummer法用石墨制备了氧化石墨烯（GO），在十二烷基苯磺酸钠存在的情况下用水合肼还原形成较高浓度的石墨烯分散液。该分散液可以稳定悬浮超过一个月。XRD、UV—vis和Raman光谱分析结果表明，所得到的石墨烯为化学反应形成的还原石墨烯（RGO）；TEM和AFM观察发现单片和多层的石墨烯并存于产物之中，说明该方法能够使RGO均匀分散于水中。

| Abstract: | Graphite oxide （GO） , prepared by modified Hummer＇s method from graphite, was reduced by hydrazine hydrate in the presence of sodium dodecylbenzene sulfonate （SDBS） , leading to a concentrated aqueous graphene dispersion which was stable for more than one month. The analyses of XRD, UV-vis and Raman spectroscopy indicate that the reduced graphene oxide （RGO） was formed after chemical reaction, where single or multiple graphene sheets were observed by TEM and AFM, indicating that the RGO is well--dispersed in water through the operation. |
