  • Morphological and rheological behaviors of micro

     · During the ultra-fine friction grinding cellulosic fibers are forced through a gap between a stator and a rotary disk. The hard surfaces of both disks disintegrate the fibers into their sub-structural components by shearing forces resulting in the fibrillation of fibers (Iwamoto et al. 2005).
