MIXED-ACID SYSTEM-BASED METHOD FOR PREPARATION OF GRAPHENE OXIDE AND GRAPHENE |
摘要 |
The present invention relates to a preparation method of graphene oxide based on mixed acid system. The method consists of the following steps. a. Preparation of graphite powder; b. Preparation of suspension liquid of first acid system; c. Preparation of second acid system; d. Preparation of graphene oxide. The invention also relates to a preparation method of graphene using graphene oxide obtained by method mentioned above. The method consists of the following steps. e. Preparation of graphene oxide-dispersant solution; f. Reduction of graphene oxide; g. Process of supersonic stripping; h. Obtaining graphene by separation and drying. The preparation methods of graphene oxide and graphene in our invention could reduce the dosage of strong acid as well as heat release of chemical reaction, and cause less corrosion to our equipments, which makes the reaction more effective and properties of graphene products better, facilitating the achievement of large scale industrial production. |
