Method for manufacturing thick graphite sheet and thick graphite sheet manufactured using same |
abstract |
The present invention provides a method for manufacturing a graphite sheet, the method comprising the steps of: carbonizing a polyimide film at a temperature of 1,250℃ or less to prepare a sheet preform containing an amorphous carbon body formed through the pyrolysis of the polyimide polymer chain; and graphitizing the sheet preform to prepare the graphite sheet containing the graphite formed through carbon-rearrangement of the amorphous carbon body, wherein the graphitization comprises a plurality of firing steps for heat treating the sheet preform at different heating rates from each other. |
