Preparation method of graphene |
| abstract |
The invention relates to a preparation method of graphene using graphene oxide. The method consists of the following steps. (1). Preparation of graphene oxide-dispersant solution; (2). Reduction of graphene oxide; (3). Obtaining graphene by suction filtration and drying process. Based on the preparation of anthracite, the invention could reduce production costs effectively comparing to traditional preparation methods of graphene, and make the reaction more fast and complete, facilitating the achievement of large scale industrial production. |
