| Abstract: | Nanocrystalline cellulose（NCC） was prepared by acid hydrolysis with copper chloride catalysis,and was characterized by using fourier transform infrared（FTIR） spectrometer,transmission electron microscopy（TEM） observation and laser particle size analysis method.The results showed that the aggregation state structure of NCC was cellulose type I.The morphology of NCC with white silk flocculent in macroscopic morphology was regular,rod-like.The size distribution of diameter and length of NCC ranges from 3 nm to 27 nm and 50 nm to 300 nm,respectively,by TEM observation.The average size of NCC is 214.3 nm with laser particle size analysis method. |
