POROUS CELLULOSE BODY AND METHOD FOR PRODUCING SAME

摘要

An object of the present invention is to provide a porous body that contains cellulose nanofibers having very thin fiber diameters and high hydrophilicity, and has a large specific surface area, and to provide a method of producing the porous body simply with low cost. The method of producing a porous cellulose body pertinent to the present invention is a method of producing a porous cellulose body, the method comprising a process of lyophilizing a mixed liquid containing cellulose nanofibers and a dispersion medium, wherein the dispersion medium is a mixed dispersion medium of water and an organic solvent dissolving in water, a concentration of the organic solvent in the mixed dispersion medium is 2 to 40 mass%, and a solid content concentration of the cellulose nanofibers in the mixed liquid is 0.001 to 5 mass%.
