Research on Performance of Vetier (Vetiveria zizanioides) Cellulose Micro/Nano Fibrils Isolated by High Intensity Ultrasonication
Abstract:
The cellulose micro/nano fibrils of Vetier (Vetiveria zizanioides) were isolated by high intensity ultrasonication in this paper. The basic properties of micro/nano fibrils were evaluated by WAXD and FTIR. The results showed that the relative crystallinity decreased when treated by high intensity ultrasonication. The characteristic absorption peak moved to higher wave number and the type of group increased with increasing the vibration of ultrasonication. The characteristic absorption peak moved to higher wave number with increasing treated time, however, the effect was insignificant.
