초록

영어
Choline chloride (CC)/lactic acid (LA) and betaine (BE)/LA, acidic deep eutectic solvents (DESs), were mixed with a ratio of 1/1, 1/2, and 1/5, and potassium carbonate (PC)/glycerol (GLY), alkaline DES, was mixed with a ratio of 1/4, 1/5, and 1/7. Wood flour (2 g) was added in the DES (98 g), and then reaction was conducted at 100, 120, and 130 °C for 6, 12, and 24h. The DES pre-treated samples were defibrillated using a high-pressure homogenizer in order to prepare cellulose nanofibril (CNF). The defibrillation operation was repeated until 7th pass at 20,000 psi. As the temperature and reaction time were increased, the weight loss was increased noticeably. At the same reaction condition, the weight loss was increased in the order of CC/LA > PC/GLY > BE/LA. The average diameters of the CNFs were in the range of 20-50 nm. As the temperature and reaction time, the average diameters were increased resulting in the increase of the filtration time.
