Deep eutectic solvent (DES) can be considered a next-generation ionic solvent consisting of a mixture of two or more compounds, one of which is a salt. The formation of new liquid compounds at room temperature is due to the formation of hydrogen bonds between the hydrogen bond donor (HBD) and the hydrogen bond acceptor (HBA), generally the halide anions present in the salt. This DES is a fairly new kind of green solvent that can be applied to various fields, and attracts much attention as an alternative to IL. This study examines the choline chloride-based DES treatment as a new pretreatment for the production of cellulose nanofibers. In the Experiments, deep eutectic solvent systems having lactic acid, urea and glycerin as the second component were formed at 100 °C and then applied to decompose wood-derived cellulose fibers. DES-pretreated fibers were nanofibrillated by mechanical treatment using a blender and their properties were analyzed. Cellulose nanofibrils with a width of 4.7 to 5.4 nm were successfully produced from DES pretreatment under all conditions. As a result, choline chloride-based DES has shown high potential as an environmentally friendly solvent in the production of cellulose nanofibrils.
