摘要
低共熔溶剂(DES)制备简单、无毒、可生物降解,是一种新兴的绿色溶剂。近几年,DES逐渐被用于生物质预处理及转化领域,具有良好的应用前景。由于DES对纤维间氢键有一定破坏作用,有利于纤维素的润胀,因此通过DES预处理结合低强度机械处理可以制备高得率的纳米纤维素。本文综述了DES在制备纳米纤维素中的研究进展,并探讨了预处理过程中发生的表面功能化对纳米纤维素的影响。
Deep eutectic solvents(DES),which are easy to prepare,nontoxic and biodegradable,is an emerging type of green solvents.In recent years,DES have been used in the field of biomass pretreatment and conversion,and have good application prospects.DES can swell cellulose and destroy hydrogen bonds between fibers.Therefore,nanocellulose can be prepared with high yields by DES pretreatment combined with low-strength mechanical treatment.In the present review,the applications and research progress of DES in the preparation of nanocellulose are reviewed,and the influence of surface functionalization on nanocellulose during pretreatment is also discussed.
