摘要：
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.
