Abstract:
A method for producing a carbon material, comprising the steps of:providing a compound having a first functional group wherein at least one hydrogen atom of said first functional group is substituted by another functional group; providing an aromatic heterocyclic copolymer precursor containing at least one functional group having heterocyclic ring forming ability by using said compound; mixing a matrix polymer with said aromatic heterocyclic copolymer precursor in an organic solvent to form a mixed solution; removing the solvent therefrom to form a coagulum; molding said coagulum with hot pressing to obtain a formed article at a temperature at which the heterocyclic ring-closing reaction does not occur; heat treating said formed article in a mold under pressure, thereby preparing a 3-dimensional mesh molecular composite material in which the heterocyclic ring-closing reaction of said functional group having heterocyclic ring forming ability occurs, thereby forming said aromatic heterocyclic copolymer; and carbonizing the resulting composite material at atmospheric pressure in an inert gas atmosphere at 2,300Â° C. to 3,000Â° C. for 2 to 6 hours.
