Cellulose aerogel and method for producing the same |
| abstract |
The present invention provides a method for producing a cellulose airgel using a solvent having an advantage in ease of handling and / or cost, particularly a specific solvent different from NMMO. A cellulose airgel having a larger nitrogen adsorption specific surface area is provided. A) Cellulose is added to an aqueous solution having 2 to 20% by weight of caustic alkali; and 4 to 20% by weight of urea or thiourea so that the amount of cellulose is 0.2 to 20% by weight. A step of dissolving and preparing a cellulose solution; B) a step of preparing a liquid-containing cellulose gel by immersing the cellulose solution in a cellulose non-solvent; C) x) drying the organic cellulose-substituted solvent, and y) exceeding A method for producing a cellulose airgel comprising: a step of critical drying or z) subcritical drying to obtain a cellulose airgel, wherein the obtained cellulose airgel has a specific surface area of 300 m 2 / g or more by nitrogen adsorption BET method. The above problem is solved by a certain method. [Selection figure] None |
