In this study, the effects of mixing treatment of endoglucanase and xylanase on characteristics of pulp and cellulose nanofibrils (CNF) were investigated. The degree of polymerization of the pulp was reduced and its crystallinity was increased after enzymatic pretreatment. The suspension viscosity of CNF prepared from enzymatic pretreated pulps was lower than that of untreated CNF. Compared with untreated CNF, more uniform and smaller fibrils could be obtained through combined pretreatment of endoglucanase and xylanase, but higher endoglucanase dosage led to wider fibrils width distribution. The aspect ratio of enzyme-treated CNF was lower than that of untreated CNF. The use of both endoglucanase and xylanase increased the tensile strength and elastic modulus of the sheet, whereas just endoglucanase-treated CNF sheet exhibited lower strength. The light transmittances of each CNF sheet were comparable; however, the casted sheet made using 1.0% endoglucanase-treated CNF was less transparent because of its morphological features. The combined use of endoglucanase and xylanase could facilitate the nanofibrillation and produce the sheet without any deterioration of strength. #Cellulose nanofibrils #enzyme #pretreatment #tensile strength #transparent film
