Abstract:

Nanocellulose has attracted much attention in many fields due to its excellent properties and unique structure. Its preparation methods and applications have become the research hotspot in related areas. At present, there are many methods for preparing nanocellulose, but they still face great challenges. Ionic liquids (ILs) have shown great potential in the preparation of nanocellulose because of their excellent solubility and recyclability to lignocellulose. Therefore, the application progress of ionic liquids in the preparation of nanocellulose was reviewed, with the focus on the achievements of ionic liquids as a pretreatment method and as both solvent and catalyst in the preparation of nanocellulose, respectively. Besides, the recovery methods of ionic liquids were also summarized.

Key words: nanocellulose, cellulose, ionic liquids, pretreatment, hydrolysis, recovery

摘要:

纳米纤维素因其优异的性能和独特的结构在很多领域都受到了关注,其制备和应用已成为相关领域的研究热点。目前纳米纤维素的制备方法众多,但依然面临着较大的挑战。离子液体因其对木质纤维素优良的溶解性能及可回收性,在纳米纤维素制备中展现了较大的潜力。基于此,综述了离子液体在纳米纤维素制备方面的应用进展,重点介绍了离子液体作为预处理手段在纳米纤维素制备方面的应用现状,以及作为溶剂和催化剂直接水解制备纳米纤维素方面的研究进展,并对制备过程中离子液体的回收情况进行了简单概述。
