摘要
通过乙酸酐对纤维素纳米晶进行表面化学修饰,得到乙酰化的纤维素纳米晶(ACN)。用XRD、FTIR以及溶解性探讨乙酰化的纤维素纳米晶的结晶性、表面官能团以及在水及有机溶剂中的溶解性。
Cellulose nanocrystals (CN) were surface modified by acetic anhydride to obtain acetylated cellulose nanocrystals (ACN). We investigate the crystalline, the surface functional groups and solubility in water and organic solvents of before and after acetylation of CN using XRD, F-FIR and TEM.
