Isolation and characterization analysis of cellulose nanocrystal from Moso bamboo
摘要
Abstract
Cellulose was extracted from Moso bamboo by carrying out bleaching and alkali treatments with acidified sodium chlorite solution and sodium hydrate solution,and then cellulose nanocrystal was isolated from extracted cellulose with the combination of (30％) sulphuric acid and ultrasonic treatment.According to the scanning electron microscopy (SEM) and transmission electron microscopy (TEM),the diameter of cellulose nanocrystal was in the range of 20-85 nm.The results of fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) showed that the hemicellulose and lignin were removed extensively from the extracted cellulose,and the crystallinity of isolated α-cellulose and cellulose nanocrystal were significantly increased.The thermal stability of bamboo at different purification stages was investigated by thermogravimetric analysis (TGA) and the thermal stability of the bamboo cellulose increased at every purification stages compared to the raw material,however,the cellulose nanocrystal showed a little Iower thermal stability than that of isolated α-cellulose.关键词
