摘　　要：纤维素基气凝胶材料的研究在近年来吸引了人们极大的关注,这是因为这类新型材料具有通常无机气凝胶的典型结构特点,如超轻、高孔率、高比表面积等,同时具有天然生物质材料的原料丰富、可再生、可生物降解的优点。本文首先简要介绍了纤维素基气凝胶材料及其发展概况,进而主要介绍了以离子液体为溶剂制备再生纤维素基气凝胶的研究进展,包括纤维素基气凝胶的制备方法、结构及其功能性。最后对离子液体法制备的纤维素基气凝胶材料的前景进行了简要的展望。Cellulose-based aerogel is a new kind of functional biomass material, which combines the advantages of typical inorganic aerogels with uitralight weight, very high porosity and specific surface area and renewable biopolymers with abundance in nature, biocompatibility and biodegradability. This review first briefly introduced cellulose-based aerogels. Then the preparation of cellulose based aerogels by using ionic liquids as solvents are discussed in detail, followed by their structure and properties. Finally, a perspective on this promising family of materials and the research that needs to be done in the future are briefly discussed.
