| Research Abstract |
The fundamental technology to extract uniform cellulose nanofibers from various kinds of plant resources has been developed. The isolation of cellulose nanofibers (CNF) by the one-time grinding treatment from wood, rice straw and potato tuber was studied. FE-SEM images showed that the diameter range of isolated microfibril aggregates from wood, 12-20 nm, was smaller than those from rice straw and potato tuber, 12-35 nm and 12-55nm, respectively. High-speed blender treatment as well as beads mill treatment has succeeded in achieving nano-fibrillation of CNF with a uniform diameter of 15-20 nm.
