Method for Preparing Thick Graphite Sheet and Thick Graphite Sheet Prepared by Using the Same |
| abstract |
The present invention comprises the steps of carbonizing a polyimide film at a temperature of 1,250° C. or less to prepare a sheet preform comprising an amorphous carbon body formed by thermal decomposition of a polyimide polymer chain; And graphitizing the sheet preform to produce a graphite sheet including graphite formed by carbon-rearrangement of an amorphous carbon body, wherein the graphitization includes a plurality of firing steps of heat-treating the sheet preform at different heating rates. It provides a method of manufacturing a graphite sheet comprising a. |
