PROBLEM TO BE SOLVED: To provide a dispersion liquid of a carbon material capable of dispersing a carbon material such as a carbon nanotube inexpensively by a simple operation, and usable as a production raw material of a molding such as a film insoluble to water containing the carbon material, and to provide a method for producing the same.SOLUTION: A carbon material dispersion liquid includes a carbon material and an aqueous solution of a cellulose-quaternary onium complex. Such a dispersion liquid can be prepared by mixing the carbon material with the aqueous solution of the cellulose-quaternary onium complex, and by dispersing the carbon material into the aqueous solution. Further, a molding such as a film insoluble to water containing the complex can be produced by removing quaternary onium complexed with cellulose by a treatment using an acid from such a carbon material dispersion liquid, to thereby deposit a cellulose-carbon material complex. |
