摘　　要：纤维素是自然界中最丰富的可再生天然高分子材料,因其强氢键网络和分层结构难以溶解和加工,限制了其功能化应用。近年来,离子液体作为新型绿色溶剂,可通过破坏纤维素氢键促进其溶解,为纤维素基材料的开发提供了新平台。本文主要探讨离子液体在纤维素提取、纤维素微球、纳米纤维素材料、纤维素基凝胶、纤维素基膜及纤维素纺织纤维等领域的应用研究成果。尽管当前离子液体在纤维素基材料开发中的应用已取得一定进展,但仍面临诸多问题,如成本高、回收困难、环境影响突出,纤维素的溶解效果及材料性能优化仍有待进一步提升。未来应重点发展低成本、环保的离子液体,改进纤维素基材料制备技术,以实现工业化应用。Cellulose is the most abundant renewable natural polymer in nature.Due to the strong hydrogen-bonding network and hierarchical structure,cellulose is often difficult to dissolve and process,thus its functional applications are highly limited.In recent years,ionic liquids have emerged as novel green solvents,which can promote cellulose dissolution by disrupting its hydrogen bonds,providing a new platform for the development of cellulose-based materials.In this review,we summarized the recent research achievements regarding the application of ionic liquids in various areas,including cellulose extraction,cellulose microspheres,nanocellulose materials,cellulose-based gels,cellulose-based membranes,and cellulose textile fibers.Despite the progress with regards to the use of ionic liquids in developing cellulose-based materials,we are still faced with numerous challenges,such as high cost,recycling difficulties,significant environmental impact,and the need for further improvement of dissolution efficiency and material performance.Future research in this field should be focused on developing cost-effective and environmentally friendly ionic liquids and improving preparation techniques for cellulose-based materials,for the ultimate goal to achieve industrial applications.
