摘要(Abstract)：

纤维素是一种广泛存在、可再生与生物降解的材料,由于在其分子内与分子间存在大量的氢键,因此它很难溶解在传统溶剂中。研究发现离子液体是一种很好的纤维素溶剂。从提高纤维素分子的可及性,利用联合溶剂和固体酸分别来增强离子液体的溶解能力等方面入手,介绍了如何能更好地使用离子液体来溶解纤维素。另外,从经济以及环保的角度考虑,介绍了一些关于离子液体回收的方法。
Cellulose is an extensively available, recyclable and biodegradable polymer. There are many in-ter-and intra-molecular hydrogen bonds in cellulose, which cause cellulose is hardly soluble in traditionaldissolvent such as water, organic dissolvent. According to the previous researches, cellulose is efficientlyand easily dissolved in ionic liquid. Starting from improving the accessibility of cellulose molecules and us-ing the combined solvent and solid acid to enhance the dissolving capacity of ionic liquid respectively, thearticle introduced how to better use ionic liquids to dissolve cellulose. In addition, from the economic andenvironmental point of view, some ionic liquid recovery methods were introduced.
