Manufacturing Method of Cellulose Nano Fibril Using Betaine-Lactic Acid Deep Eutectic Solvent |
| abstract |
In the method for producing cellulose nanofibers using the betaine-lactic acid eutectic solvent of the present invention, since the fine wood flour is pretreated with the betaine-lactic acid eutectic solvent, the efficiency of mechanical pulverization and fibrillation is increased to produce cellulose nanofibers with small diameter and homogeneous. There are advantages that can be Betaine, a hydrogen bond acceptor of the present invention, can be easily removed by simply washing the pretreated fine wood flour with distilled water, so it has an economical advantage compared to the conventional eutectic solvent using choline chloride. |
