纤维素纳米纤维很好的结合了纤维素的重要属性和纳米材料的各项特性,但纤维素大分子之间存在大量氢键,使得纤维素较难溶于普通溶剂,导致通过静电纺丝法直接制备纤维素纳米纤维具有一定的难度。而先采用静电纺丝法制备纤维素衍生物纳米纤维,再对纤维素衍生物纳米纤维进行水解也是制备纤维素纳米纤维的一种有效方法。本文对近年来这两种纤维素纳米纤维制备方法的研究进行了综述,并对静电纺制备纤维素纳米纤维的发展前景做出了展望。
Cellulose nanofibers combine well the important properties of cellulose and various properties of nanomaterials, but there are a large number of hydrogen bonds between the cellulose macromolecules, making cellulose more difficult to dissolve in common solvents, resulting in the use of electrospinning Direct preparation of cellulose nanofibers has a certain degree of difficulty. The first use of electrospinning preparation of cellulose derivatives nanofibers, and then hydrolysis of cellulose derivatives nanofibers is also an effective method for the preparation of cellulose nanofibers. In this paper, the preparation of these two kinds of cellulose nanofibers in recent years are reviewed, and the prospect of electrospinning cellulose nanofibers is also prospected.
