    摘要: A one-step (direct graphitization) process for producing a graphitic film, comprising directly feeding a precursor polymer film, without going through a carbonization step, to a graphitization zone preset at a graphitization temperature no less than 2,200° C. for a period of residence time sufficient for converting the precursor polymer film to a porous graphitic film having a density from 0.1 g/cm3 to 1.5 g/cm3 and retreating the porous graphitic film from the graphitization zone. Preferably, the precursor polymer film is selected from the group consisting of polyimide, polyamide, phenolic resin, polyoxadiazole, polybenzoxazole, polybenzobisoxazole, polythiazole, polybenzothiazole, polybenzobisthiazole, poly(p-phenylene vinylene), polybenzimidazole, polybenzobisimidazole, polyacrylonitrile, and combinations thereof. Preferably, the precursor polymer film contains an amount of graphene sheets or expanded graphite flakes, preferably from 1% to 90% by weight, sufficient for promoting or accelerating graphitization.
