METHOD FOR MANUFACTURING POROUS CELLULOSE PARTICLES AND POROUS CELLULOSE PARTICLES |
| 摘要 |
Provided are a method of manufacturing porous cellulose particles, including a cellulose solution preparation step of preparing a cellulose solution by dissolving cellulose in an aqueous lithium bromide solution, a dispersion preparation step of preparing a cellulose solution dispersion by dispersing the cellulose solution in an organic dispersion medium, and a coagulation step of coagulating cellulose in the cellulose solution dispersion by cooling the cellulose solution dispersion and adding a coagulation solvent thereto such that porous particles are obtained, and porous cellulose particles obtained by the method for manufacturing porous cellulose particles. |
