METHOD AND APPARATUS FOR MODIFYING GRAPHENE |
| 摘要 |
There are a method and an apparatus for modifying a graphene, and more specifically, a method and an apparatus for modifying a graphene capable of obtaining the graphene having a desired crystallite size by repeating a process for modifying the graphene using subcritical or supercritical carbon dioxide several times. According to the method and the apparatus for modifying the graphene of the present invention, the graphene having excellent electrical conductivity and dispersibility may be obtained. |

1. A method for modifying a graphene comprising:
injecting carbon dioxide in a liquid state into a reactor having the graphene;modifying the graphene by temperature-raising and pressure-raising carbon dioxide to 20 to 50° C. and 73 to 200 atm, respectively;
pressure-releasing and cooling the modified graphene; and recovering the pressure-released graphene by a recovering bath filled with deionized water. |
