| titleOfInvention | A kind of preparation method of cellulose nanofibril aerogel suitable for layer-by-layer self-assembly process |
| abstract | A method for preparing a cellulose nanofibril aerogel suitable for a layer-by-layer self-assembly process, comprising the following steps: 1) dispersing cellulose nanofibrils in water to obtain a dispersion; 2) dispersing polyethyleneimine The aqueous solution is diluted to a concentration of 15%; 3), the cellulose nanofibril dispersion obtained in step 1) is mixed with the polyethyleneimine aqueous solution obtained in step 2) to make it evenly dispersed, and then left to stand to obtain cellulose nanofibrils with stable structure Filament hydrogel; 4), the cellulose nanofibril hydrogel obtained in step 3) is firstly subjected to gradient pre-freezing, and then freeze-dried to obtain the cellulose nanofibril aerogel. The aerogel prepared by the invention has high wet strength, high shape stability in water, compressibility and recoverability. |
