초록

A process for making an artificial graphite film from a graphitizable polymer is described. In the process, a starting polymer film having a defined thickness is thermally treated at a temperature of not lower than 2400°C. in an inert gas to graphitize the film, and rolled to obtain a graphite film. The graphite film has good flexibility and elasticity with relatively smooth surfaces.
