摘　　要：纤维素是自然界中最丰富的资源之一,以纤维素为原料制备的第三代气凝胶兼有传统气凝胶的高孔隙率和大比表面积以及本身优异性。然而,固有的可燃性、较差的力学性能和较低的热稳定性限制了其使用范围。目前将纤维素气凝胶进行功能化,开发多种功能化的复合气凝胶已成为研究热点。从纤维素气凝胶的制备过程,功能化方法,以及主要应用领域进行了概述,最后对功能化纤维素气凝胶存在的问题进行了讨论。Cellulose is one of the most abundant resources in nature.The third-generation aerogels prepared from cellulose have both the high porosity and large specific surface area of traditional aerogels and their own advantages.However,its inherent flammability,poor mechanical properties and low thermal stability limit its application.At present,the functionalization of cellulose aerogels and the development of a variety of functionalized composite aerogels have become a research hotspot.In this paper,the preparation process,functionalization methods and main application fields of cellulose aerogels are summarized.Finally,the problems of functional cellulose aerogels are discussed.
