GRAPHENE MATERIAL AND METHOD OF PREPARING THE SAME |
摘要 |
A method of preparing a graphene material. The method includes: (1) preparing a liquid polyacrylonitrile (LPAN) solution, stirring the LPAN solution to yield a cyclized polyacrylonitrile solution; (2) stirring the cyclized LPAN solution at between 200 and 300°C to yield a thermally-oxidized polyacrylonitrile; (3) grinding and sieving the thermally-oxidized polyacrylonitrile, and drying a resulting product at room temperature, to yield a thermally-oxidized precursor; (4) calcining the thermally-oxidized precursor in the presence of an inert gas flow of between 10 and 500 mL/min for between 1 and 24 hrs at the temperature of between 400 and 1000°C, to yield a carbonized precursor; and (5) calcining the carbonized precursor in the presence of an inert gas flow of between 10 and 500 mL/min for between 1 and 10 hrs at the temperature of between 1000 and 3000°C, to yield a graphene material. |
