摘　　要：纳米微晶纤维素来自天然高分子聚合物,具有成本低、强度高、轻便等特点,并可循环利用或者生物降解。纳米微晶纤维素研究倍受关注,但纳米微晶纤维素存在一些实用方面的困难。制备过程复杂、热稳定性差等是限制纳米微晶纤维素大规模商业化应用的主要的因素。本文综述了纳米微晶纤维素的热降解机理及其热稳定性影响因素,探讨了提高其热稳定性的途径。Nanocrystalline cellulose（ NCC）isolated from biomass has attracted great attention as a novel nanostructure material due to its low cost,excellent mechanical properties,biodegradability and renewability. However,there are still many challenges that need to be overcome in the application of nanocrystalline cellulose,including large-scale production of nanocrystalline cellulose and improvement of its thermal stability. This paper reviewed the mechanism of nanocrystalline cellulose thermal degradation and summarized the factors which affected its thermal stability. The progress of the methods in improving thermal stability was discussed.
