资源简介：
The disclosure provides a method for preparing cellulose nanofibrils by deep eutectic solvent pretreatment， characterized in that the method comprises: Si. Deep eutectic solvent pretreatment: a chemical pulp is added to the deep eutectic solvent to obtain a mixed solution; S2. Separation of the treated pulp fibers: water is added to the reaction system in step Sl to terminate the reaction， and then the pulp fibers are separated from the mixed solution; S3. High-pressure homogenization microfluidization: the pulp fibers separated in step S2 are formulated into a slurry having a particular slurry concentration， then subjected to high-pressure homogenization microfluidization， and then spray-dried to obtain a cellulose nanofibril product. In this disclosure， the preparation conditions are mild; the operation is simple; the cost is low; and the pollution is small; the used deep eutectic solvent can be recovered by methods such as rotary evaporation and the like and therefore can be reused; it is environmentally friendly， meets the standards of green chemical production， and has good practical application value.
