摘　　要：纤维素能够在离子液体中溶解并结晶,在纤维素结构、高分子结晶理论研究方面和光学、生物医用材料等领域表现出巨大价值。针对纤维素/离子液体体系,在晶体结构、形貌和应用三方面综述了一些进展,归纳总结了纤维素的多晶型结构及在离子液体中纤维素的晶体结构及晶体形貌,简述了纤维素结晶的相关应用。最后探讨了在该体系相关研究中存在的问题,并展望了未来的发展方向。In ionic liquids （ILs）, cellulose can be dissolved and crystallized, which exhibits enormous value in theoretical study on cellulose structure and polymer crystallization as well as in the field of optical and biomedical materials.Based on cellulose/ILs system, progress in crystal structure, morphology and application is reviewed. Both the polymorphs of cellulose and its crystal structure and morphology in this system is summarized, and the application of cellulose crystallization is briefly introduced. The existing challenges and future prospects are discussed at last.
