Abstract

In this paper, nanocellulose fibers (NCFs) from the fruit bunch fiber (FBF), leaf blade fiber (LBF), and leaf sheath fiber (LSF) of windmill palm were prepared by sulfuric acid hydrolysis. The microstructure, surface physical property, chemical composition, and crystallinity index were studied. The results showed that the nanocellulose fibers from fruit bunch (FBNCFs), nanocellulose fibers from leaf blade (LBNCFs), and nanocellulose fibers from leaf sheath (LSNCFs) were successfully prepared with a thickness of 5 nm, and a diameter of 31 ± 8, 28 ± 7, and 27 ± 8 nm, respectively. The NCF from FBF was the softest sample, which can make a soft nanocellulose film. The adhesion force of LSNCF was the highest at about −11.78 ± 2.99 nN. Sulfuric acid treatment removed most of the hemicellulose and lignin.

摘要

本文采用硫酸水解法制备了风车棕榈果束纤维（FBF）、叶片纤维（LBF）和叶鞘纤维（LSF）的纳米纤维素纤维（NCFs）。研究了显微结构、表面物理性能、化学成分和结晶度指数。结果表明，成功制备了果串纳米纤维素纤维（FBNCFs）、叶片纳米纤维素纤维（LBNCFs）和叶鞘纳米纤维素纤维（LSNCFs），厚度为5 nm，直径为31±8，分别为 28 ± 7 和 27 ± 8 nm。来自 FBF 的 NCF 是最柔软的样品，可以制作柔软的纳米纤维素薄膜。LSNCF 的粘附力最高，约为 -11.78 ± 2.99 nN。硫酸处理去除了大部分半纤维素和木质素。
