Abstract:This paper summarized the research progress of the applications of cellulose nanocrystal （CNC） and cellulose nanofibril （CNF） in enhancing biodegradable polymers. Two kinds of nanocellulose material and their preparation methods were introduced. The strengthening mechanism of nanocellulose material and the preparation methods of composite materials were elaborated. In addition， this paper demonstrated the research progress of nanocellulose in the application of reinforcing polylactic acid （PLA）， thermoplastic starch （TPS） and polycaprolactone （PCL）. Finally， the challenges of the scale-up and industrialization of nanocellulose material reinforced biodegradable polymers were briefly analyzed， and its application potential was prospected.
