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.
