Abstract
In this study, the effect of delignification degree of Korean white pine wood on fibrillation efficiency by wet disk-milling (WDM) and the properties of thus-obtained microfibrillated cellulose (MFC) were investigated. The effect on the tensile properties of nanopaper was also investigated. The delignification degree was adjusted by repeating 'Wise' method using sodium chlorite and acetic acid. The increase in delignification degree improved fibrillation efficiency, showing the smaller nanofiber dimension at the shorter WDM time. The filtration time of MFC water suspension was increased by the increase of WDM cycles. Tensile strength and elastic modulus of the nanopaper were increased by increasing delignification degree and disk-milling cycles.
