| Abstract:In this study， the relationship of absorbance and diameter of cellulose nanocrystal （CNC） was investigated by the suspension absorbance method. The results showed that when the CNC was 0.06 wt% with the test wavelength of 220 nm for 0 h， the absorbance value of CNC dispersion gradually decreased with the increase of CNC particle size. There was a good linear relationship between CNC diameter and absorbance， of which the linear equation was that Y（absorbance）=-0.0054X（CNC diameter）+0.4438， with a linear correlation R2 of 0.9931. |
