摘要
The focus of this study has been to isolate cellulose microfibril aggregates by the one-time grinding treatment from wood, rice straw and potato tuber, and to compare their morphological and mechanical properties. Field emission scanning electron microscopy 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 12-55 nm, respectively. These differences were observed even in the purified rice straws and potato tuber before the grinder treatment, but were hardly observed in the purified wood. The results of X-ray analysis and tensile tests indicated that there were no significant differences among the sources in the cellulose crystallinity and Young's modulus of the isolated microfibril aggregates in the dry state. These results suggest that the inherent characteristics of cellulose microfibril aggregates in the dry state are very similar regardless of plant sources and tissue functions.
