摘　　要：采用氧化还原法制备石墨烯,首先以石墨粉为原料,利用Hummers法先制备了氧化石墨,再使用水合肼还原氧化石墨获得石墨烯.通过SEM和TEM对制备的石墨烯进行表面形貌和结构观察,利用X射线衍射和热重分析进一步确认所制为石墨烯.分析表明,所得石墨烯层数较少,热稳定性比氧化石墨更高.This paper prepared graphene by Oxidation-Reduction method. Using graphite powder as initial mate- rial, firstly prepared graphite oxide by Hummers method, then using Hydrazine Hydrate to reduce graphite oxide and the graphene was finally gained. The surface morphology and structure of samples were characterized by SEM and TEM, and the dealultimated samples were confirmed to be graphene through XRD. Comprehensive analysis shows that the graphene prepared here has very few layers and high thermal stubility.
