摘要：In this work, lignocellulosic nanofibrils (LCNF) produced from mechanical fibrillation with mixed enzymatic pretreatment or post-treatment were compared and the chemical composition, water retention value (WRV), average-number height and crystallinity for the obtained LCNF were evaluated. Compared to pure mechanical fibrillation, both mixed enzymatic pretreatment and post-treatment could efficiently facilitate cellulose nano-fibrillation. Moreover, mixed enzymatic pretreatment was more suitable for LCNF production, resulting in a relatively higher WRV of 909% and smaller average-number height of 15 nm. These discoveries provide new insights into a more efficient biological method for the production and application of cellulose nanomaterials.
