Fundamental study on the extraction of uniform nanofibers from plant-biomass

从各种植物资源中提取均匀纤维素纳米纤维的基本技术已经发展起来。研究了从木材、稻秆和马铃薯块茎中一次性粉碎分离纤维素纳米纤维（CNF）。FE-SEM图像显示，木材中分离的微纤维聚集体直径范围为12 ~ 20 nm，小于稻秆和马铃薯块茎中分离的12 ~ 35 nm和12 ~ 55nm。高速混合机处理和珠磨处理成功地实现了直径均匀为15-20 nm的CNF纳米纤颤。

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.
